<p>PURPOSE:To offer an accumulator capable of setting a wide pressure adjusting range. CONSTITUTION:Inside a cylinder 51, which is formed on an accumulator body 52 which a free piston 53 stored therein, is divided into No.1 and No.2 chambers 54, 55, while a passage 56, which communicates to the No.1 chamber 54 and passes pressure oil through, is formed on the accumulator body 52 and a coned disc coned disc spring 59, which presses the free piston 53, is provided in the No.2 chamber 55. A pressure adjusting range covering a wide range can be set because the coned disc spring 59, which deflects and resists the pressure oil force actuating on the free piston 53, makes more deflection and resists the pressure oil when the pressure is strong but less deflection when pressure oil is weak.</p> |
