Japanese Patent JP2021173327
Kind Code:
A
Abstract:
To provide a pulsation attenuation device capable of increasing a surplus elastic energy capacity of an elastic body capable of being used in pulsation absorption.SOLUTION: A pulsation attenuation device 1 of a fluid pressure circuit comprises: an internal flow path 2 forming a part of the fluid pressure circuit; a fluid pressure chamber 3 provided at a position facing the internal flow path 2; and an elastic body 4 provided so as to separate the internal flow path 2 and the fluid pressure chamber 3, where the fluid pressure chamber 3 is provided so that pressurized fluid can be circulated between itself and the fluid pressure circuit; the elastic body 4 can receive fluid pressure from each of the internal flow path 2 and the fluid pressure chamber 3; and an area difference is provided between a flow path side pressure receiving area S1 and a flow path side pressure receiving area S2.SELECTED DRAWING: Figure 1
