摘要

A fill and relief valve arrangement for the introduction of fluid into and the selective venting of fluid from a fluid chamber includes a body having a stepped open-ended bore extending therethrough and an annular shoulder formed at one end of the bore. A valve seat element is sealingly secured within the other end of the bore and has a passage formed therein communicating with a passageway which communicates the bore with the fluid chamber. A fill valve is adjustably positioned within the bore and has a first position in engagement with a valve seat element for isolating the fluid chamber from a vent port open to the atmosphere and a second position for establishing communication between the passageway and the vent port for venting the fluid chamber to the atmosphere. The fill valve is confined between the valve seat element and the annular shoulder.
