Claim:
A hydraulic accumulator, comprising: an accumulator housing having a gas chamber adjacent a gas access and a fluid chamber adjacent a fluid access, said chambers being located within said housing and separated by a separating element; a fluid connecting piece of said fluid access; a valve support located in said connecting piece and having several fluid passages arranged diametrically relative to a longitudinal axis and opposite to one another; a plate-like valve body integrally connected by a valve shaft to said valve support, said valve body tapering toward said valve shaft on a side thereof facing said valve support, said valve body and said valve support being movable together along said longitudinal axis within said connecting piece between an open position projecting into said fluid chamber and a closed position in which a plate edge of said valve body engages said connecting piece, said valve support being guided for movement by an outside surface thereof engaging an inside surface of said connecting piece, said valve shaft defining inside borders of said fluid passages; an energy accumulator, located underneath said valve body and between said valve body and said connecting piece, biasing said valve body toward said open position to allow fluid to be conveyed from through said passages and said energy accumulator and allowing said valve body to move to said closed position by said separating element; and a stop in said connecting piece engaged by said valve support in a maximum possible open position of said valve body, said stop being a sealing ring fitted in a recess on said inside surface of said connecting piece.
