とする油圧緩衝器の圧縮側減衰力発生機構。The piston at the tip of the piston rod is slidably inserted into a cylinder filled with hydraulic oil, and the oil pressure is set to 12 to generate damping force during the compression stroke through the oil hole in the bottom piece fixed to the bottom bolt at the bottom of the cylinder. In the damping force generation mechanism of the shock absorber, the oil passage 16 communicates with the shaft of the bolt 7 into the cylinder 2 and the bottom piece 11 from the oil passage 16.
Forming an orifice 17 that communicates with the lower oil reservoir 12,
A check valve 18 having a center hole 20 through which oil passes is slidably fitted into the oil passage 16, and a valve spring 19 engaged with the check valve 18 moves the valve 18 above the orifice 17. A compression-side damping force generation mechanism for a hydraulic shock absorber, characterized in that the orifice 17 is opened and closed by a check valve 18 that slides up and down in accordance with the oil pressure of an oil passage 16.
