る油圧緩衝器の圧縮側減衰力発生機構。The piston at the end of the piston is slidably inserted into the cylinder filled with hydraulic oil, and the oil hole in the bottom piece fixed to the bottom bolt at the bottom of the cylinder generates damping force during the compression stroke. In the damping force generation mechanism of the hydraulic shock absorber, an oil passage 16 that communicates with the shaft of the bottom bolt 7 into the cylinder 2 and a bottom piece 11 from the oil passage 166
An orifice 17 communicating with the oil sump 12 below is formed [,
7. 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 interposed below the check valve 18 connects the check valve 18 to the orifice. The orifice 17 is opened and closed by a check valve 18 that is supported above the oil passage 17 and slides up and down according to the oil pressure in the oil passage 16. Furthermore, an adjustment rod 22 is attached to the center bolt 9 below the bottom bolt 7 and protrudes to the outside. The valve spring 19 is vertically displaced by the adjustment rod 22, which is fitted in a vertically movable manner and brought into contact with the spring receiver 23 below the valve 18.
A compression side damping force generation mechanism for a hydraulic shock absorber, characterized in that the preset load of the hydraulic shock absorber is adjusted.
