Valve for a hand held spray nozzle
摘要：
A hand held spray nozzle (10) for a kitchen faucet has a valve housing (12) with an elongated passage (20) and a valve seat (28). A valve element (36) has a frusto-conical elastomeric sleeve (40) engageable to the valve seat (36) and has a camming surface (44) mounted upstream from the elastomeric sleeve (40) and a stabilizer flange (48) mounted further upstream from the camming surface (40) and a spring seating end (50) which seats a biasing spring (58) which biases the valve element to the closed position. A push rod (62) engages the camming surface (44). The push rod (62) is canted from the vertical position at approximately (60) degrees and has an outer end (75) engaging a pivoting handle (78) where the thumb engaging section (82) is at a wall opposite abutment section (76) which engages the outer end (75) of the push rod (62).
