Abstract
A shock absorber for damping the relative movement of the sprung portion of the automobile with respect to the unsprung portion of the automobile. The shock absorber includes a pressure cylinder and a piston disposed within the pressure cylinder. The piston is able to control the flow of damping fluid between the first and second portions of the working chamber so as to generate firm and soft damping characteristics. The shock absorber also includes a reserve cylinder disposed exterior of the pressure cylinder, and a base valve disposed at one end of the pressure cylinder. The base valve is operable to control the flow of damping fluid between the second portion of the working chamber and the reserve chamber in response to the flow of damping fluid between the first and second portions of the working chamber.
