Abstract: A fluid spray apparatus has an inlet assembly and an outlet assembly that are rotatable with respect to each other. The inlet assembly attaches to a fluid supply and has an outlet opening through which the fluid passes. The outlet assembly has a plurality of inlets positioned to communicate with the outlet opening as the outlet assembly is rotated into different positions with respect to the inlet assembly. Each inlet communicates with a different passage through the outlet assembly and has a set of openings that form a unique spray pattern. One of the fluid passages includes a circular chamber in which a forced vortex is created by the fluid flow. A turbine valve is disposed in the chamber and is driven by the vortex to alternately cover and expose one set of openings. The turbine valve and a chamber wall have rough textured surfaces to reduce friction. The turbine valve is made of an acetal plastic filled with silicone and polytetrafluorethylene to further reduce friction.

Abstract: A valve assembly for insertion into a valve body. The valve assembly includes a valve insert adapted to be positioned axially within the valve body. The valve insert has a longitudinally extending fluid passageway therethrough including an inlet opening at one end in communication with a source of fluid under pressure and an outlet opening at the other end remote from the fluid source and includes a seal disposed between the valve insert and the valve body to only permit flow of the fluid through the fluid passageway. In addition, the valve insert includes a sealing surface extending about the outlet opening. The valve assembly also includes a valve stem adapted to be in axially positioned alignment with the valve insert.

Abstract: A faucet and liquid supply tube therefor. The faucet includes a body portion defining a valve chamber having a discharge opening communicating with a spout together with an inlet opening adapted to communicate with a liquid supply line. It also includes a control valve received in the valve chamber and having an inlet passage communicating with the inlet opening together with a discharge port communicating with the discharge opening. The liquid supply tube has an area of increased wall thickness defining an enlarged head terminating in a shoulder at the end thereof associated with the inlet opening together with a substantially uniform inner diameter for carrying liquid from the supply line into the inlet passage. In addition, a seal is associated with the enlarged head externally of the liquid supply tube.

Abstract: A mixing faucet valve having a check valve in each liquid supply line to prevent syphoning of liquid and crossover of liquid into a supply line in the event of reduced pressure in a line. The valve also includes a Venturi type arrangement for automatically diverting the outflow of liquid from a principal discharge spout to an auxiliary spray hose attachment when the valve to the spray hose is opened.

Abstract: A mixing faucet valve having a single check valve to prevent syphoning of liquid into a supply line in the event of reduced pressure in a line. The valve also includes a Venturi type arrangement for automatically diverting the outflow of liquid from a principal discharge spout to an auxiliary spray hose attachment when the valve to the spray hose is opened.
