ActiveUS20120048666A1Improve coaxialityDecrease productivitySpringsLiquid based dampersEngineeringSliding contact
A piston connected to a piston rod is fitted in a cylinder having a hydraulic oil sealed therein. Flows of hydraulic oil induced by sliding movement of the piston are controlled by extension and compression damping force generating mechanisms and to generate damping force. In the extension damping force generating mechanism, the valve-opening pressure of a disk valve is controlled by the pressure in a back pressure chamber. An elastic seal member fixed to the disk valve is brought into sliding contact with an inner peripheral surface of a cylindrical portion of a valve member to seal the back pressure chamber. The disk valve is self-aligned by fitting between the elastic seal member and the inner peripheral surface of the valve member and secured by being axially clamped at an inner peripheral portion thereof in a state where a clearance is formed between the inner peripheral portion of the disk valve and a shaft portion of the piston rod, thereby reducing the requirements for coaxiality.
