Abstract: A diverter valve for a faucet directs water to either the faucet spout or a spray nozzle. The faucet assembly of the present invention includes a shuttle chamber from which water may access either of two outlet paths. A poppet valve selectively enables water flow from the shuttle chamber to the outlet path leading to the faucet spout whenever the water pressure in the outlet path leading to the spray nozzle is greater than or equal to the pressure in the shuttle chamber. When the spray nozzle is actuated, pressure in the outlet path leading to the nozzle is relieved and the poppet valve closes off the outlet path leading to the faucet spout. A bypass channel is provided between the shuttle chamber and the outlet path leading to the spray nozzle, thereby allowing water to flow through the nozzle while it is actuated. A precision sized orifice in the bypass channel maintains the pressure differential acting on the poppet valve so that flow to the faucet spout remains cut off while the spray nozzle is actuated.

Abstract: This invention relates to a single-handled valve for controlling both combined volume and relative proportion of hot and cold water. A control valve stem extends between diametrically disposed moldable sealing members, the sealing members respectively cooperating with hot and cold water inlet openings. The axial and angular positions of the stem determine the combined volume and relative proportion while the sealing members perform all of the sealing functions between the inlet openings and the valve outlet.
