段を設けたことを特徴とする液圧緩衝器。 The piston rod is equipped with a disc valve opening control mechanism that controls the opening of the disc valve that controls the opening of the piston's extension-side orifice when the piston rod moves on the extension side. The space is divided by a check sheet into a liquid chamber communicating with the liquid chamber on the valve seat side and a pressure side liquid chamber, and an outgoing orifice and a return orifice communicating the liquid chamber with the pressurizing side liquid chamber are formed in the check sheet. At the same time, a solid particle dispersion solution is sealed in these liquid chambers, a liquid chamber disc valve is provided on the check sheet to close the outlet side of the outgoing orifice, and the check sheet is deformed in response to the temperature of the solid particle dispersion solution. A sensitive member is provided to control the movable range of the liquid chamber disk valve, the outlet side of the return side orifice is closed openable/closed by a check plate, and the disk valve is pushed into the valve seat side liquid chamber in the direction in which the return side orifice closes. 1. A hydraulic shock absorber, characterized in that a valve seat is movably provided, and a voltage applying means for applying a voltage to a solid particle dispersion solution is provided in the liquid chamber.
