Claims

[Scope of utility model registration request]

In a shock absorber, a piston is slidably inserted into a cylinder to define upper and lower oil chambers, and a damping valve is provided to provide resistance to hydraulic oil flowing in and out between the upper and lower oil chambers as the piston moves up and down. A variable orifice that senses vehicle acceleration and increases or decreases the opening degree is installed in the middle of the passage that communicates the two oil chambers, and this variable orifice allows a valve unit with an internal throttle port to selectively rotate. A shock absorber comprising:
