    Abstract: PURPOSE: An accumulator of a hydraulic striking system is provided to prevent a boundary surface between a diaphragm and a metal or non-metal plate from being deformed and to absorb effectively shock pressure of the working fluid by making the diaphragm thin. CONSTITUTION: In an accumulator of a hydraulic striking system, an accumulator body(110) is branched and connected to a pipe through a fluid inlet port(120). A diaphragm(150) divides the inside of the accumulator body into a fluid inlet chamber(130) of the fluid inlet port and a gas chamber(140) in the opposite side. A diaphragm(150') of the fluid inlet port of the flexible diaphragm is thick. A metal plate(170) having an inclined end(160) at the periphery is molded and combined in the diaphragm of the fluid inlet port to restrict a radial deformation in a boundary surface between the diaphragm and the metal plate.

    Abstract: 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 restrains 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).
