Abstract: There is disclosed a pressure-compensated mixing valve of the diaphragm and reciprocating piston type, wherein a flexible connection between the diaphragm and the pistons is provided. This flexible connection affords a self-alignment of the pistons in water inlet passages. In a preferred manner, this is used with a mixing valve providing alignment of a ported ring member that also provides in part an internal stop feature.

Abstract: A toilet has a pump to deliver selected quantities of water from a reservoir to a toilet bowl so as to effect a water savings. In one aspect, both the motor and pump are positioned in the reservoir to deliver water to both the rim and bowl portions. In another aspect, there are conduits connected between the basin, the rim and controls which are provided to deliver water to the rim and bowl either independently, simultaneously or in selective sequences. In alternative embodiments, a refill tube is connected to an intake conduit and the rim of the bowl to effect a water seal, a fail safe valve is connected to the supply conduit, a receptacle with a cleaning fluid and a pump is connected to the bowl and there are at least two receptacles for receiving waste.

Abstract: An apparatus for pulsing water flowing to a shower head includes a housing with a chamber, first and second water inlets to the chamber and a water outlet. The second inlet and the outlet are located through a wall of the housing at one end of the chamber. A valve has a plate with a plurality of apertures. The valve disposed within the chamber so that water flowing through the first inlet urges the valve into close proximity to the housing wall where rotational movement of the valve alternately opens and closes the water outlet. That action creates a pulsed flow of water through the outlet. Water flowing into the chamber through the second inlet moves the valve plate away from the housing wall permitting water to flow continuously from the second inlet into the outlet without being pulsed. A mechanism is coupled to the valve to produce the rotational movement.

Abstract: A sink assembly is disclosed that has a separate rim and basin made of different materials. The basin has a flange surrounding a bowl that is exposed under the rim to form an accessible ledge. A glass-filled polyester resin is injected into a mold adjacent the underside of the rim member and the flange. The polyester resin bonds with the rim member and prevents the basin from moving relative to the rim member.
