摘要: A hydraulic accumulator (14) is equipped with a novel shut-off valve. The shut off-valve includes a valve body (21) having a cylindrical hollow with a valve seat (37) surrounding one end. The main piston (24) including a piston head has a central opening (30) and is slidably mounted within the cylindrical hollow of the valve body. A poppet valve (22) has a valve head which mates with the valve seat and a valve stem which extends through the central opening of the piston to guide axial movement of the poppet valve relative to the piston. A spring (23) is mounted between the valve head and the main piston head for urging the valve head away from the piston head. A control valve (27) moves the piston relative to the valve body between open and closed positions responsive to signals from a computer (72) which signals valve closing upon determination that flow rate through the valve exceeds a maximum period. The spring between the poppet valve head and the piston head exerts a force approximately equal to that of a pressure drop across the poppet valve at a predetermined maximum flow rate.

摘要: An outside gas type accumulator has a mechanism for reducing the pressure difference occurring when liquid confined in a liquid chamber and gas filling the liquid chamber in zero-down state expand thermally, and restrain abnormal deformation of a bellows by reducing the pressure difference between the inside and outside of the bellows. A pressure difference regulation mechanism (21) reduces the pressure difference occurring when liquid confined in the liquid chamber (11) and gas filling the liquid chamber in the zero-down state expand thermally. The regulation mechanism (21) has a movable plate (22) supported by a coil spring (23) on the oil port (4) side of a bellows cap (8) . During normal operation, the plate (22) moves together with the cap (8) by being supported by the spring (23), and the plate (22) moves together with the cap (8) and to be brought into contact with a seal (13) in the zero-down state. When the liquid and the filling gas expand thermally, the plate (22) maintains contact with the seal (13), and the cap (8) moves up to a position where the liquid pressure and the gas pressure are balanced while compressing the spring (23).
