Abstract
A fluid control valve comprising a valve housing in which there is a reciprocating shaft on which is mounted a valve body that is brought into and out of contact with respect to a valve seat disposed within a fluid flow passage to permit or prevent fluid flow through the passage. The valve includes a vibration retarding mechanism comprising a sleeve mounted on the shaft and a guide mounted to the housing with an axial opening sized to receive the sleeve. Either the sleeve or guide has slots and the other has corresponding grooves that receive the slots to limit the radial movement of the shaft to retard or dampen reciprocation-induced vibrations.
