ABSTRACT:
A faucet diverter to be mounted within a portion of a water faucet assembly for controlling water flow to either a faucet spout or a spray discharge includes a body, a chamber within the body, and a water inlet opening into the chamber. There is a spout outlet and a spray outlet connected to the chamber and there is an orifice in the body between the chamber and the spout outlet. A poppet is movable within the body chamber and carries a cone seal adjacent one end to control flow through the orifice to the spout outlet. There is a cup seal carried by the other end of the poppet to control flow to the spray outlet. The cup seal has an outwardly-extending lip formed and adapted to be in contact with a wall of the chamber and the cup seal has a generally annularly disposed recess at the end away from the lip. There are a plurality of outwardly extending projections on the exterior of the cup seal, bearing against the chamber wall, and being located generally in alignment with the recess. The cup seal is formed of an elastomeric material which distorts under pressure from water within the chamber, with the result that water pressure in the recess causes distortion of the cup seal toward the chamber wall between the cup seal projections.
