Abstract: A showerhead is disclosed with a control surface about the lower periphery of the showerhead that can be continuously rotated through 360 degrees to control the water spray patterns exiting the showerhead. The control surface is mechanically linked by a cam track and mating cam followers to a set of plungers in the showerhead faceplate. The plungers can be axially moved within openings in the faceplate of the showerhead by rotation of the control surface. That axial movement of the plungers allows a user's adjustment of the spray patterns exiting the showerhead.

Abstract: An application head for applying, in a non-contacting way, liquid media to a length of material which is movable relative to the application head. The head includes a housing, a cylinder chamber in the housing, in which cylinder chamber a cylinder slide is rotably drivably supported, and a nozzle for ejecting medium, which nozzle can be controlled by the cylinder slide and extends transversely to the direction of movement of the length of material. The cylinder slide includes a cylindrical surface which, from the inside, can seal supply means leading to the nozzle. The cylinder slide also includes at least one surface groove in the cylindrical surface, which surface groove can be supplied with liquid medium and which, as a function of the rotational position, is able to communicate with the supply means leading to the nozzle. The at least one surface groove includes delimiting edges with a variable gradient relative to the circumferential direction.

Abstract: An improved nozzle assembly for spraying cooling water into superheated steam flowing through a steam pipe of a steam desuperheater includes a nozzle housing, a nozzle barrel, a valve element, and at least one valve spring. A nozzle barrel disposed within the nozzle housing has flow passages in fluid communication with a barrel chamber. The barrel chamber minimizes a tendency for cooling water to enter the superheated steam in a streaming spray. The valve element is slidable within the nozzle barrel for regulating the flow of cooling water through the nozzle assembly. The valve spring biases the valve element against the forward end of the nozzle housing to initially seal the nozzle assembly in a closed position. A control valve increases the fluid pressure within the nozzle housing which in turn forces the valve head away from the nozzle housing, allowing for increased flow of cooling water into the superheated steam.

Abstract: A spray assembly for use in a kitchen includes a body with a first section and a second section extending from the first section. The body includes an inlet defined in a first end of the body and connected to a water source. A first chamber is defined in the first section and communicates with the inlet. A second chamber is defined in the second section and extends to a second end of the body. A path is defined in the body and communicates with the first chamber and the second chamber. A piston is reciprocally received in the body to close the path. A trigger is pivotally on the body to downward drive the piston to open the path. A sprinkling device is mounted to the second end of the body for controlling water current that sprinkles from the sprinkling device.

Abstract: This disclosure relates to an improved foam aeration nozzle comprising a peripheral jet nozzle, a spray collector which receives the jet and produces a fully filled spray, and an aeration device which agitates and aerates the spray and produces the foam. In use, the peripheral jet nozzle produces an annular cone-shaped spray or sheet of water. A collector is attached to the nozzle, the collector including a tubular wall in the path of the conical spray. The collector further includes an annular obstruction, and the water, as it moves along the wall surface, strikes the obstruction. At least a portion of the water is deflected toward the axis of the nozzle by the obstruction to produce a fully filled spray. An aeration device downstream of the obstruction is located to be impinged by the fully filled spray and to convert the spray to a foam and to discharge the foam on an intended target at a useful distance.

Abstract: A shower head has a body forming a rear compartment pressurizable with water and a forwardly open mouth having an inner periphery and an end disk generally closing the mouth, extending perpendicular to an axis, and having an elastically deformable outer rim formed with a plurality of axially through-going and radially outwardly open grooves opening rearwardly into the compartment and radially outwardly closed by the body. The rim further is formed with an annular and elastically deformable lip projecting axially past a downstream face of the disk and a downstream end of the body. The grooves are formed in the lip. Thus the critical downstream ends of the flow passages constituted by the grooves are formed in an elastically deformable lip that can be deformed. Since the deposits are normally very hard, such deformation of the lip will flake any lime deposits off.

The transfer conduit assembly is adjustable in length by use of a spring loaded fitting that allows for an outer transfer conduit along with the fitting to be in axial slidable engagement around an inner transfer conduit.

Abstract: The object of the invention is to provide a thin, close curtain of liquid, for instance in fire-fighting. According to the invention, this is achieved by use of a nozzle having a central control body which is movable within an outer sleeve, both the control body and the outer sleeve having gently tapering wall portions facing each other. The gently tapering portion of the control body merges smoothly into the rear side of a disc-shaped end portion provided thereon, such that the liquid, in a thin layer, will follow the central control body and be deflected into a substantially radial direction relative to the nozzle so as to form a liquid curtain directed transversely in relation to the nozzle.

Abstract: A multifunction nozzle including a peripheral jet nozzle having a first end adapted to be connected to a liquid supply and a second end from which the jet is ejected. The liquid may be plain water or a mixture of water and a foam concentrate. The peripheral jet nozzle is adjustable between straight stream and fog positions. The multifunction nozzle further comprises a sleeve which is attached to and surrounds the peripheral jet nozzle, the sleeve being movable relative to the jet nozzle in the direction of the nozzle axis and the flow of the liquid. The sleeve is movable between a forwardly extended or foam position and a rearwardly retracted or inoperative position. When the sleeve is in the retracted position it is out of the path of the liquid jet and the nozzle may be used in either the straight stream or fog modes. When the sleeve is moved forwardly to the extended position and the peripheral jet nozzle is placed in the fog mode, the diverging liquid jet strikes the inner surface of the sleeve.

A pair of slidable, annular rings contained in the body adjacent the inlet port comprise an upstream ring and a downstream ring. Each of the rings are spring biased from the other. The upstream ring includes a flow passageway and a flow obstructing portion. The downstream ring includes a plurality of flow passageways, at least one of said downstream ring flow passageways being disposed out of communicable flow alignment with the upstream ring flow passageway.

Abstract: The shower spray apparatus has a hollow housing with three spray exit openings in a common face, two for normal spray and the third for pulsating spray. Incoming pressurized water is fed into a diverter which includes a slide valve adjustable to proportion the flow of water along either of two paths exclusively, or in a continuous variable range between the two paths. The first path of fluid flow from the slide valve terminates in the two normal spray exit openings, while water flowing along the second flow path drives a turbine and exits via openings in the pulsating outlet. The rotating turbine includes a mask which sequentially covers and uncovers the spray outlet to provide the pulsating output. A knob on the spray apparatus housing is adjustably rotatable to operate a slide valve throughout a full range of adjustment, providing either all normal spray, all pulsating spray or any ratio therebetween.
