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.
