Abstract: A spray head is disclosed which is capable of generating a pulsating spray and is particularly suited for domestic shower and bath use. The spray head employs a rotor which, as it is turned by flowing water, axially reciprocates to alternately open and restrict a water flow passageway through the spray head. Means are also provided for adjusting the spray head to provide a continuous spray with the rotor continuing to rotate, thus reducing the risk of rotor clogging or freezing.

Abstract: A shower head is disclosed of the type having a pivotally mounted spray head. The shower head comprises a first member adapted for attachment to a water supply pipe and a spray head pivotally mounted to the first member. The first member includes a concave, socket-defining surface with a water supply aperture therein. The spray head has an inner spray body, through which the water flows, and an outer retaining sleeve, which secures the spray body to the first member. To prevent leakage between the spray body and the sleeve, an annular seal is carried by the spray body and slidably engages the concave surface of the first member along a line which encloses the water supply aperture at all pivot positions of the spray head. In the preferred embodiment, the inlet end of the spray body defines a flow-limiting vortex chamber, into which water is directed in a swirling action.

Abstract: A single lever faucet assembly having a faucet control lever which is reversibly mountable laterally on either side of the faucet spout without having to switch positioning of the hot and cold water supply lines thereto. The faucet assembly includes a valve cartridge which may be easily disconnected from the faucet control lever and removed from the faucet base for replacement. The valve cartridge is arranged and disposed to provide a straight through flow path from the hot and cold water supply lines to the faucet spout which is free of any obstructions, thereby maximizing outlet flow rates. The faucet assembly further includes a means for independently controlling discharge temperature and flow rate by separate-patterned movement of the faucet control lever so as to provide uniform temperature regulation at any flow rate.

Abstract: A Roman tub fixture assembly for mounting a spout to the exposed spout side of a wall or deck having an exposed spout side and an opposite facing hidden side includes a receiver body which is adapted to couple to one or more water pipes located on the hidden side of the wall or deck. A flanged nut is threadably received over the body in order to mount the body within an opening in walls or decks of different thicknesses. A spout hub having a shank portion and a shoulder portion is threadably received along the shank portion within a passageway in the receiver body. The shank portion includes two cylindrically shaped sections which have different diameters, the larger diameter section having external threads and the smaller diameter section having sealing means in order to seal the space between the body and the hub at a location upstream from the threaded portion of the body passageway.

Abstract: A valve assembly for use in building water systems where hot and cold water supply line pressures vary, and having separate valve means for regulating the hot and cold water pressures. Independently mounted pressure equalizing means operated by the supply water pressures are connected to operate each of the valve means responsive to any pressure differential caused by changes in the supply pressures, to change the water pressure regulated by each of the valve means, with the magnitude and sense of the change reducing any such differential to zero and equalizing the pressures. The separate valve means are actuated by diaphragm assemblies forming a pair of movable walls mounted in a cartridge each one separating one water chamber from an associated hydraulic fluid chamber. Each diaphragm movable wall assembly includes a nonperforated diaphragm clamped between elements and held at its periphery in the cartridge to form a movable wall.

The separate valve means and pressure equalizing means are contained in a cartridge having separate supply water chambers and hydraulic fluid chambers associated with each water chamber.
