ABSTRACT:
A shank of the valve reciprocates within a hydraulic fluid-receiving chamber, and a cap, detachedly confined with the chamber cooperates with the shank to define a dashpot. The dashpot serves to decelerate the final closing of the valve to minimize wear of the valve head and the seat against which it closes.
