Valve for a hand held spray nozzle
First Claim
1. A valve characterized by:
- a housing having an upstream end constructed to be secured to a flexible hose and a downstream end having a fluid outlet and a valve seat;
a movable valve element axially movable along an axis between an open and closed position;
a push rod canted with respect to said axis;
an annular frusto-conical camming member affixed upstream of and to said valve element for abutting said push rod;
a handle means for axially moving said push rod against said camming means for axially moving said valve element upstream to said open position; and
biasing means for biasing said valve element to said closed position.

Abstract
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).

3. A hand held nozzle characterized by:
-
a housing having an upstream end constructed to be secured to a flexible hose and a downstream end having a fluid outlet and an elongated passage therebetween with an interior housing wall circumscribing said passage; a valve seat mounted about said passageway in said housing; a valve element axially movable along an axis of said elongated passage between an open position and closed position with respect to said valve seat; said movable valve element having a frusto-conical elastomeric section sized to abut against said valve seat; a camming section mounted upstream of said frusto-conical elastomeric section; a stabilizing element axially spaced upstream from said camming section and radially sized approximately the same as said camming section to be slightly spaced from said interior housing wall to prevent said movable valve element from being overly canted from the axis of the elongated passage; a push rod slidably mounted with respect to said housing and canted with respect to said passage axis; said push rod having an inner end abutting said camming section and an outer end extending outside of said housing; operating means for pushing said push rod against said camming section to move said valve element to said open position; and biasing means for biasing said valve element to said closed position. - View Dependent Claims (4, 5)

6. A valve characterized by:
-
a housing having an upstream end with a fluid inlet, a downstream end having a fluid outlet and an elongated passage therebetween with an interior housing wall circumscribing said passage; said interior wall having an annular shoulder with a small radius section forming a valve seat between a narrow section and wider section of said elongated passage; a plunger type valve element mounted for axial movement in said elongated passage between an open position and closed position with respect to said valve seat; said valve element having an elastomeric section having a frusto-conical shape sized to abut against said small radius section of said shoulder in said elongated passage;
said frusto-conical elastomeric section forming an angle of substantially less than 45°
with respect to the longitudinal axis of the valve element;a drive means positioned upstream of said valve seat for driving said valve element to said open position; a biasing means for biasing said valve element to said closed position; said drive means including; push rod canted with respect to said valve element; a camming surface fixedly positioned on said valve element for abutting said push rod, said camming surface positioned upstream of said elastomeric section; and a handle means abutable against an outer section of said push rod and operable for moving said push rod to push against said camming member and move said valve element upstream to an open position. - View Dependent Claims (7, 8, 9, 10, 11)
