ABSTRACT:
A pressure-responsive valve unit is received in the cavity of a valve assembly housing, the inner end of the cavity being connected with a fluid container. The valve unit includes a main body having a chamber containing a check valve body that is movable toward and away from engagement with a valve seat on the main body, the valve seat facing the check valve body and the inlet end of the cavity, and the main body having passage means communicating fluid from the container to the front end portion of the check valve body. The check valve body is biased into engagement with the valve seat by a spring, the force of which is adjustable with a plug threaded into the inner end of the main body chamber. An outlet bore extends from the outer end of the main body to the valve seat, and the check valve body is engageable by a push rod inserted through said outlet bore.
