Abstract
A faucet diverter valve for directing water to either a faucet discharge or to an alternate water flow device such as a spray includes a valve body having an inlet, a faucet outlet, and an alternate water flow device outlet. There is a chamber in the valve body with the inlet and outlets opening into the chamber. A stationary diverter valve member is positioned within the chamber. A portion of the diverter valve member and the chamber wall form a restricted water flow passage therebetween. There is a water passage in the valve member connecting the valve body inlet and the upstream side of the restricted passage. The alternate water flow device outlet is located at the downstream side of the restricted passage. The valve member has openings therein positioned adjacent to and in communication with the restricted water flow passage. There is a flow path in the valve member connecting the valve member openings and the faucet outlet. When there is no water flow to the alternate water flow device, water from the valve body inlet flows to the restricted water flow passage, through the valve member openings and to the valve body faucet outlet. When the alternate water flow device is opera…
