ABSTRACT:
A fill and vent valve assembly has a bore in a first member and a cylindrical stem of a second member positioned within the bore. A blind bore extends inwardly from an inner end of the stem and has an internal threaded section. First and second passages in the stem communicate the blind bore with a passage device which communicates the bore of the first member with a fluid chamber. A fill valve has an external threaded section threaded into the internal threaded section of the stem and is movable between a first position at which a valve seat of the valve is in sealing engagement with the inner end of the stem and the first and second passages are blocked from communication with ambient and a second position at which the valve seat is spaced from the inner end and the second passage is in communication with ambient for purging air from the fluid chamber in response to fluid being forced through the fill valve and into the fluid chamber through the first passage.
