Abstract
A variable rate shock absorber having the interior of a working cylinder divided by a piston into an upper and lower working chamber. The lower working chamber is connected to a reservoir by a bi-directional valve member. A solenoid valve housed in a hollow piston rod has an actuated state connecting the upper working chamber to the reservoir. The output of the solenoid valve is connected to the reservoir by means of an axially disposed telescoping cylinder passing through the piston and the bi-directional valve member.
