A valve for controlling an opening for the passage of fluid into and out of a pressure accumulator has a valve member, which, by the elastically expanding membrane of the pressure accumulator, can be brought against the force of a spring to a closed position. An orifice plate located in the valve housing creates a pressure difference to opposite sides of the plate, and this pressure difference is directed to opposite sides of a piston operably connected to the valve member to thereby bias the latter to the open position during outflow of fluid from the pressure accumulator, to thus prevent a premature movement of the valve member to the closed position.
