Beschreibung
Zusammenfassung:	A small, reliable diverter valve that maintains a relatively constant flow through a spray nozzle in spite of water supply pressure fluctuations and that positively terminates flow from the faucet spout during hand spray operation. A variable elasticity cup seal keeps constant area passageway to the spray nozzle in spite of water supply fluctuations. A normally open path, moreover, enables air to flow from the spout into the water supply system in conditions of negative supply pressure and thereby assists the cup seal in preventing backflow from the spray nozzle into the fresh water supply.
