Claims

[Scope of utility model registration request]

(1) A piston rod is slidably inserted into the cylinder via a piston, the piston defines two oil chambers, upper and lower, in the cylinder, and an orifice port is bored in the piston to communicate the two oil chambers, In a hydraulic shock absorber, a leaf valve is installed at the end of the orifice port so that it can be opened and closed.
Multiple opening chambers with different opening cross-sectional areas are formed on the end face of the piston.
A damping force generating device for a hydraulic shock absorber, wherein an orifice port communicating with one or more of the opening chambers is selectively oriented in one direction.

(2) The damping force generating device for a hydraulic shock absorber according to claim 1, which is a registered utility model, in which three opening chambers having the same cross-sectional area and an opening chamber having a larger cross-sectional area are equally distributed.

(3) A damping force generating device for a hydraulic shock absorber according to claim 1, wherein an open chamber and a leaf valve are provided on both end faces of the piston.
