Abstract
A fluid diverter controls water flow through a faucet assembly which includes a spout and a handspray. The diverter includes a housing and a shaft mounted therein for reciprocal movement, with a piston and a cup valve mounted on opposite ends of the shaft. When water is supplied to the faucet assembly and the handspray is turned off, water pressure builds up within a first compartment of the diverter between the piston and the cup valve such that the cup valve is moved off its seat to establish water flow through a first outlet passageway to the spout. When the handspray is operated, water from the interior of the diverter flows through a second outlet passageway leading to the handspray, and also into a second compartment on the opposite side of the piston. A differential pressure is achieved between the two compartments by providing a notch of a selected size in an annular rim portion of the housing at the second outlet passageway. The size of the notch is made sufficiently large so that particle contaminants pass easily through the diverter.
