特徴とする油圧緩衝器の減衰力調整装置。 In a hydraulic shock absorber, a piston attached to the tip of a piston rod is slidably fitted into a cylinder, and this piston is provided with an oil passage that communicates the upper and lower oil chambers and a valve that opens and closes this oil passage. The valve is held between piezoelectric ceramic compositions that expand and contract in response to voltage, and the damping force is adjusted by changing the preset force on the land surface of the bulb by changing the voltage applied to the piezoelectric ceramic composition. Damping force adjustment device for hydraulic shock absorbers.
