Abstract: A shower head for selectively discharging therefrom, alternatively and respectively from one of two sets of apertures, a regular shower spray or a pulsating shower spray is inexpensively provided by the use of molded parts that include a shell and a downstream housing which telescopes into the shell, and with diverter means provided, by a molded diverter body and a pivotable diverter shaft therein, for selectively directing the water that enters the diverter body to one or the other of the two sets of apertures associated with the downstream housing. The pulsating shower spray is achieved by means that includes a propeller, and a molded nozzle plate that directs incoming water in streams against the propeller, whose movement past the set of discharge apertures operates to provide a pulsating discharge therefrom.

Abstract: A flow controller, for limiting total maximum water flow through a domestic flow appliance, is provided by a molded flexible body shaped to provide a deformable central flow orifice and an outermost sealing section that is adapted to be operatively positioned at the joint between a supply conduit and the flow appliance, such as a showerhead, aerator, or the like. Associated with the flow controller are: (1) an annular tubular support for positioning the portion of the flexible body with the deformable central flow orifice upstream of the sealing section, and (2) a cavitation noise reducer located immediately downstream of said central flow orifice. The cavitation noise reducer has specific construction features for use with specific appliances, and may also be provided with a downstream tubular flow straightener, or simulator, of selected length and width dimensions to effectively develop a frictional effect that reduces undesirable sound that normally accompanies use of a flow controller.

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: An aerator, that includes jet-defining slots and jet-fragmenting surface therein formed of or in molded plastic parts, is provided with a self-cleaning character that is achieved by providing a washer-shaped body that effects, upon initial flow of water into the aerator, a directed liquid flow at an increased velocity to effect a scrubbing action of the jet-defining slots to dislodge debris therefrom, and a plug member providing an open flow passageway through which the dislodged debris is then discharged, after which the flow passageway is automatically closed by a valve member and normal steady state aeration conditions then prevail in the aerator.

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 coupling for dishwashers is provided with a unitary molded plastic body having two nipples extending therefrom, for connection to supply and discharge hoses, and with a separation wall with integral flow deflector, disposed within the molded body for separating flow channels therein and for rigidifying the unitary body. The coupling body is provided with quick connect coupling elements at the upstream end and molded splash preventer means at the discharge end of the coupling.

Abstract: A quick connection coupler for securement to a complementary nipple is produced principally of plastic parts by using molded slide-type cam jaws in a molded tubular body for gripping the nipple, and by using a molded downstream seal retainer telescoped into the coupler body for supporting a downstream packing that is to effect a seal with the downstream end of the nipple. The seal retainer preferably provides a valve thereon that operates automatically to close and prevent back flow through the coupler when the coupler is separated from the nipple, and to be opened for flow therepast upon connection of the coupler to the nipple.
