Abstract: The oral hygiene device comprises a nozzle-holder connectable to a liquid source and a nozzle (1) removably attached to the nozzle-holder, the nozzle being intended for spraying either a multi-jet of liquid via a first duct or a single jet of liquid via a second duct. A two-way valve (5) makes it possible to direct the liquid towards one duct or the other and therefore the branching of the two liquid ducts are located in the nozzle itself. There is a restoring spring (27) which is such that the stable position of the device is for multi-jet spraying, while under the action of an external force exerted on the control member (6) of the valve the device assumes the single-jet position.

Abstract: A dispensing cap for a container, the cap being of the type which has a movable spout mounted on a nozzle having outlet passages. The spout is movable between one position in which it blocks flow through the outlet passages and another position in which it permits flow through the outlet passages. The improvement involves the additional formation of one or more discharge passages in the nozzle which are not controlled by the spout. Such additional discharge passages may be of the type which provide an angled discharge stream, a high pressure discharge stream, a mechanically broken up spray or a high volume discharge flow. A separate closure member may be provided for the additional discharge passages.

Abstract: A water spraying nozzle of the present invention is constructed of a relatively small number of parts which can be easily assembled to produce the water spraying nozzle at a low cost, which nozzle is easy in handling to enable any user to smoothly operate it without any special training. In the water spraying nozzle of the present invention, the outer and intermediate sleeves employed in the conventional water spraying nozzle are replaced with a novel controlling sleeve comprising an inner and an outer sleeve portions enabling the user to operate the water spraying nozzle in a very simple manner.

Abstract: A showerhead including an inlet end and an outlet end. The inlet end of the showerhead body forms a spiral chamber which produces a rotating current of water. An inner disc having a series of ports therethrough is positioned immediately adjacent to an outer disc which also has a series of ports therethrough. A spinner, on the inlet end of the inner disc, rotatably driven by the rotating current of water, has open and closed portions which pass in sequence across certain of inner disc ports producing a pulsating water stream therethrough. The outer disc is rotationally adjustable relative to the inner disc. The ports of both discs are arranged in concentric rings such that as the outer disc is rotated relative to the inner disc, varying throughpaths are achieved as the outer disc ports align with the inner disc ports. Four spray modes are achieved: (1) a variable regular spray, (2) combination pulsating and regular spray, (3) variable pulsating spray, and (4) variable pulsating misting spray.

Abstract: Hand showers of different functions all have the same casing, which comprises solely channels of non-specific function and non-specific connection means for carrying water. A first inner insert comprises complementary, non-specific connection means, by which a connection to the casing for the water is provided as well as channels of exclusively large area carrying water and which now have a specific function. Finally, all the channels carrying water, which possibly tend to become blocked on account of their small cross section, and all other parts possibly requiring maintenance are combined in an outer insert of specific function, into which the water flows from the inner insert.

Abstract: An air distribution system, particularly for automobiles, in which the depth of the unit is relatively short and in which control over the direction of air flow can be achieved by movement of an element in a plane orthogonal to the direction of air flow. A main air flow outlet is formed in a wall member and a parallel flow path is formed adjacent the outlet and has diverging walls which are relatively short so that there is no wall attachment or coanda effects per se. Flow of fluid through the adjacent parallel flow path exits through an opening that directs the air in a direction generally parallel to the short wall direction of the adjacent flow path. By controlling the entry of air into the parallel flow path, the main air flow vector is deflected and the direction of flow is thereby controlled. The deflection is greater when an obstacle slightly intrudes the side of the outlet opposite the parallel flow path.

Abstract: A showerhead includes a housing which defines different sets of spray outlets and includes a mounting for the housing that defines a path of water flow from an inlet. Formed on the housing are circumferentially-spaced grooves and formed on the mounting are mating lugs. Lands disposed between successive ones of the grooves include a cam surface which elevates in continuation toward the entrance of a next groove and then terminates in a step leading toward the bottom of that next groove, as a result of which the assembly atop the lands and subsequent movement of the lugs over the cam surface lockingly drops the lugs into corresponding ones of the grooves. The mounting includes a handle through which water flows and which is removably received within arms of a bracket to which water is supplied and therefrom led into the handle. A channel within the body of the bracket accepts a shank projecting from a pivot ball which sealing seats within a nut that, in turn, is threaded onto a water-supply pipe.

Abstract: A shower head contains a cup-shaped casing with a longitudinally displaceably held core part, for whose displacement an eccentrically-mounted circular disc engages in an opening of the core part. The eccentrically-mounted circular disc contains an eccentrically arranged hole, through which engages a square section of an adjusting member. Within the casing, the adjusting member is mounted in a sleeve in part of the shower head which does not carry water. The adjusting member does not require packings.

Abstract: A showerhead has a series of orifices together with a series of spray outlets and a turbine with a valve for sequentially opening successive ones of the orifices. The turbine is driven by water emitted from a nozzle. A multiply-apertured flow director plate communicates water to the nozzle, the orifices and the outlets. Overlying the director plate is a control plate that selectively couples water to different ones of the apertures in the director plate as the latter is moved by a control ring. First, second and third passages are defined in the showerhead, the first between an aperture in the director plate to the nozzle and also through the valve to the orifices, the second from an aperture in the director plate to the outlets and the third from an aperture in the director plate in bypass of the nozzle but through the valve to the orifices in a manner to retard the speed of the turbine.

Abstract: A safety spray wand with a selectively adjustable or interchangeable tip. The wand will selectively provide a high pressure or a low pressure discharge from a discharge tube. The wand has a handle with a pistol grip in combination with a large squeeze trigger. The pistol grip is extended and is molded around a receiving tube that projects downwardly from a discharge tube to thereby form a safety protection guard for an operator's hand while protecting the trigger from accidently being actuated. The receiving tube not only serves as a guard but also as a conduit to which a pressure source is attached and through which the fluid is directed to the discharge tube.

Abstract: A mixing device is disclosed for the purpose of mixing a first fluid with a second fluid contained in a pressurized stream.

Abstract: A fluid-spray discharge apparatus has a housing associated with a fluid inlet. Also associated is a fluid outlet and an arrangement for effecting pulsation of fluid delivered from the inlet to the outlet. The outlet is composed of a series of spaced-apart fluid conveyances. Associated with the housing are means for enabling selection of the number of the series of conveyances operative in the flow of the fluid. Also included is an arrangement of fluid dischargers disposed outwardly of the conveyances and fluid emitters disposed inwardly of the same. Internal diverters and channels enable the provision of fluid delivery from any of the combinations of entirely from the emitters, entirely from the dischargers, in a mixture from the emitters and the dischargers, entirely from the conveyances and in a mixture from the dischargers and the conveyances.

Abstract: An adjustable massage shower head comprising, a housing defining a liquid input chamber for receiving a liquid, a flow guide mounted for axial movement in the housing defining a liquid flow passage from the input chamber and a turbine chamber, the flow guide having a spray bottom connected thereto with openings therethrough. A rotor valve is rotatably mounted and fixed at an axial position to the housing and disposed in the turbine chamber for rotation which produces a pulsating spray from the openings. A ring wall is disposed around the turbine chamber and has a plurality of ducts extending radially at an oblique angle therethrough for directing liquid against the rotor valve. The flow guide is axially movable to direct liquid against increasing areas of the rotor valve to increase the frequency of the pulsing spray.

Abstract: An adjustable shower head for producing adjustable sprays comprising, a housing, a liquid supply connection connected to the housing for the input of liquid into the housing, and a slide bushing mounted for rotation and axial movement in the housing which has an inclined slot defined thereon and a toothed rim which is engageable by a pinion which is rotatably mounted on the housing wall. The pinion carries a guide pin which is flushly engaged within the inclined slot for axial movement of the slide bushing when the pinion is rotated. At least one spray element is fixedly connected to the slide bushing for producing an adjustable output spray of liquid.

Abstract: A spray and aerator faucet appliance is provided by a construction wherein the selection of water discharge is effected by merely rotating the water discharge head portion of the appliance until the desired water discharge from the appliance appears. Selectivity is achieved by providing two abutting internal parts, each with a flow passageway located eccentric of the axis of the appliance, with seal means for the eccentric flow passageway provided between the abutting parts, for permitting selection either of flow only through the eccentric flow passageways when aligned, or no flow through the eccentric passageways when not aligned, thereby permitting discharge of flow through an alternate flow path. Each of the two abutting internal parts is locked internally of the appliance to one of the two portions of the appliance between which relative rotation is effected by rotating the discharge head. All parts of the appliance, except for the seals and screens, are inexpensively executed in plastic.

Abstract: An improved faucet spout attachment is provided for selectively delivering therefrom either an aerated stream or a spray of liquid. The attachment is inexpensively manufactured and provided by an adapter and a body member. The adapter is shaped to provide thereon both an upstream annular head and a reduced diameter downstream nipple. The adapter's nipple has its exit passageway only in the nipple's longitudinal wall. Two seals are provided on the nipple both up-stream and downstream of the exit passageway. A seal is provided on the adapter's annular head. The body member is axially elongated and constructed to slidingly cooperate with both the head and nipple of the adapter to provide two liquid tight seals at alternate axial positions for the body member. The body member is shiftable axially between two operative positions that establish alternate paths of flow from the body member, one of which produces a spray while the other path leads to a discharge opening in which an aerator is positioned.

Abstract: A shower head that employs a rotor for effecting a pulsed jet-discharge is embodied in a construction by means of which the user may selectively secure either a pulsed jet-discharge or continuous spray discharge from the shower head. The rotor is housed between upstream and downstream housing parts that are axially movable between pulsed discharge and spray discharge positions, by relative rotation of said upstream and downstream housing parts through a screw-threaded connection so that the user's selection between pulsed jet-discharge and continuous spray is achieved by a simple rotary motion of the downstream housing part. A selectively releasable stop member limits rotation in one direction to insure proper axial spacing of said upstream and downstream housing parts when pulsed jet-discharge is selected.

Abstract: A shower head comprises a water chamber and attachment means for connecting the water chamber to a water conduit. A rotor in the water chamber is rotated by swirling motion of the water and causes pulsating emission of water from holes in an end face of the water chamber. A movably mounted outer casing has windows formed therein to allow the pulsating emission through. Changing the position of the outer casing causes water to be emitted continuously from holes formed in the outer casing and sealed from the windows.

Abstract: A pulsating spray nozzle has a number of features including the introduction into the outer periphery of a forced vortex of a speed-control fluid. In such a forced-vortex environment, a floating turbine is enabled by means of paths correlated with outlet openings better to avoid stalling. Improved dimensioning of elements in the forced-vortex-turbine approach also contributes in that direction. A regulator limits the rate of flow of fluid through the device to a predetermined maximum amount upon increase of incoming water pressure beyond a selectable level.

Abstract: A sprayer has a hollow housing with an inlet port and an outlet opening. A cap assembly closes the outlet opening and includes a plurality of sets of discharge orifices with each set exhibiting an individually different characteristic of orifice flow of fluid from the housing interior. The orifice sets are selectively opened to the passage of flow out of the housing and that flow is valved. Different sets of the orifices provide for a fine-spray cone, larger streams and a swirling jet. A porting seal cooperates with a selector plate to enable fluid communication to different sets of orifices and an overall valving assembly also is included. Still further is a stand for the sprayer which supports it, when desired, above a holder or in a manner which enables convenient storage.

Abstract: An improvement of a power controlling apparatus is included in a showerhead.

Abstract: A conduit is traversed by a screw, which screw may or may not be capable of rotating within the conduit, the screw alone, or the screw together with the conduit, become rotatable around their common axis when fluid under pressure enters from one end of the conduit, exits from the other by traversing the helical path of the screw. The construction in which the screw is rotatable within the conduit is found suitable for producing a pulsating stream of water and for building showerheads for selectively producing different types of streams, such as (a) pulsating stream, (b) spray, and (c) soft bubbly aerated stream. Various valves manually operated by a part of the showerhead perform the selection. The pulsating stream is achieved by a screw having helical threads that makes a snug fit with the inside wall of a cylindrical pipe through which the water flows; the flow rotating the screw which in turn operates a valve that at least partially interrupts the flow of water through an outlet orifice.

Abstract: A showerhead having an axially shiftable valve means to deliver either a continuous steady water spray or an intermittent or pulsating water spray. The head has a peripheral chamber through which water flows to provide the continuous steady shower spray and an inner chamber through which the water flows to provide the pulsating shower spray. The valve means travels only 0.200 inch in shifting from the pulsating spray position to the continuous spray position. In the pulsating spray position, the valve means blocks the path of water flow through the outer chamber by a seat-seal arrangement to direct the water into and through the inner chamber. In the continuous spray position, the valve means blocks the flow of water through the inner chamber by a bore seal arrangement to direct the water path through the peripheral chamber.

Abstract: A shower head is provided capable of producing a pulsating or steady spray. Water entering the shower head passes through a set of inlet orifices into a plenum chamber and drives a turbine-type rotor within the chamber. The rotor has water cutting vanes which alternately open and close one or more water outlets from the chamber. The water then passes from the water outlets to the user for pulsed spray, or is directed to smaller openings for steady spray.In the pulsed spray condition the total water outlet opening area is about four times the area of the inlet orifices to the plenum chamber, resulting in low back pressure, rapid rotation of the rotor and so pulsating spray. In the steady spray the smaller openings have a total area approximating that of the plenum inlet orifices, resulting in a high back pressure within the plenum chamber. This high back pressure causes the chamber to fill with water and serves to slow or stop rotation of the rotor.

Abstract: A shower head is provided which can, alternatively, provide a fine, steady stream of shower water or a coarser, pulsating stream of shower water to produce a massaging effect. All of the water stream is, initially, pulsed, but the pulsation is removed when a steady stream is desired.The incoming water enters the spinner of a Hero's engine axially; it causes rotation of the engine spinner as it leaves the tangentially directed exit spouts of the engine. The water then enters a chamber having a circular outlet cover plate carrying small peripheral holes and larger, more centrally located holes inside the periphery.A rotatable dial plate is positioned between the circular outer cover plate and the plenum chamber. This plate has holes in it which can be aligned with the large inner massaging holes, with channels leading to the outer peripheral holes, or at a position in between. The position of the dial plate is controlled by an associated control arm.
