ABSTRACT:
A valve assembly includes a housing and a valve plunger slidably mounted within the housing, which carries a pair of valve engaging, ringlike elements for engagement with corresponding seats on the plunger. The cross-sectional diameter of one of the ringlike valve elements is substantially greater than the other, and fits on the plunger with clearance to permit it to be deformed and deflected relative to the plunger to assure a proper sealing engagement of the other ringlike element. A collar retains the other ringlike element, and acts against the valve seat to limit movement of the plunger relative to the housing.
