The invention relates to a hydropneumatic accumulator in which a bladder or membrane supported within a vessel establishes a chamber for confining a compressible fluid within the vessel and also provides means for supporting a valve plate opposite inlet and outlet ports arranged so that as the valve plate position responds to pressure changes normal flow between the ports may be maintained and extruding of the bladder or diaphragm into the outlet port prevented.
