ことで一方の油室を高圧に他方の油室を低圧にし
、高圧の油室から低圧の油室へバルブ構造を介し
て作動油を流通させることで減衰力を発生するよ
うにした油圧緩衝器において、前記バルブ機構は
スリツトバルブを含み、このスリツトバルブを支
持するバルブシートには減衰力発生の際に前記高
圧の油室と低圧の油室との中間の圧力となる中間
圧室を形成したことを特徴とする油圧緩衝器の減
衰力発生用バルブ機構。 By sliding the piston along the circumference of the cylinder, one oil chamber is made to have high pressure and the other oil chamber is made to be low pressure, and hydraulic oil is circulated from the high pressure oil chamber to the low pressure oil chamber via the valve structure. In a hydraulic shock absorber designed to generate a damping force, the valve mechanism includes a slit valve, and a valve seat supporting the slit valve has a valve seat located between the high pressure oil chamber and the low pressure oil chamber when the damping force is generated. A valve mechanism for generating damping force of a hydraulic shock absorber, characterized by forming an intermediate pressure chamber that generates pressure.
