Abstract
Abstract A solenoid actuated fluid control valve comprises a porting member including a port and a conical valve seat circumscribing the port, and a relatively movable port closing valve element such as a needle valve element including a resilient conical tip. The valve seat and tip are correspondingly tapered and a small annular bead is provided on the resilient tip which provides for initial and preferably total sealing of the valve. Also provided is a suitable stop such as a shoulder on the needle valve element body adjacent the resilient conical tip thereon which engages an opposed surface on the porting member to prevent overcompression of the resilient conical tip and preferably to limit sealing contact to the area of the sealing bead.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
131 words
In a fluid control valve comprising a porting member including a port and a conical valve seat circumscribing said port, and port closing means including a valve element having an elongated rigid body and a resilient conical tip secured at one end of said rigid body, said valve seat and tip being correspondingly tapered and said porting member and valve element being relatively movable to open and close said port at said valve seat and tip, the improvement comprising a relatively small, annular sealing bead on, concentric with, and projecting from the correspondingly tapered surface of said tip for effecting sealing engagement between said tip and seat; in combination with stop means provided to limit the amount of compression of said annular bead and tip when engaged with said valve seat.
Claim 2
Dependent Claim
131 words
In a fluid control valve comprising a porting member including a port and a conical valve seat circumscribing said port, and port closing means including a valve element having an elongated rigid body and a resilient conical tip secured at one end of said rigid body, said valve seat and tip being correspondingly tapered and said porting member and valve element being relatively movable to open and close said port at said valve seat and tip, the improvement comprising a relatively small, annular sealing bead on, concentric with, and projecting from the correspondingly tapered surface of said tip for effecting sealing engagement between said tip and seat; in combination with stop means provided to limit the amount of compression of said annular bead and tip when engaged with said valve seat.
