PROBLEM TO BE SOLVED: To improve the mounting property of a pressure accumulation device.SOLUTION: An accumulator 100 includes: a housing 101 including a cylindrical portion 102; a piston 120 movably disposed in the cylindrical portion 102 so as to divide a pressure accumulation chamber 150 with the cylindrical portion 102; a spring 130 disposed in the cylindrical portion 102 so as to be positioned on the opposite side to the pressure accumulation chamber 150 to the piston 120, and energizing the piston 120 to the pressure accumulation chamber 150 side; and a solenoid valve S1 which permits the inflow of oil from a supply oil path L1 to the pressure accumulation chamber 150 when closing the valve, regulating the outflow of the oil from the pressure accumulation chamber 150 side to the supply oil path L1, and permits the outflow of the oil from the pressure accumulation chamber 150 to the supply oil path L1 when opening the valve. The solenoid valve S1 is attached to an outer peripheral portion of the cylindrical portion 102.SELECTED DRAWING: Figure 4 |
