12MS1287/1285r 223-86-0170 A VARIABLE RATE SHOCK ABSORBER and SYSTEM THEREFOR Abstract: The invention describes an electrically controllable mono-tube shock absorber (10) wherein the damping of the shock absorber is controlled by a solenoid valve (60). The valve (60) includes a poppet valve (150) which is mechanically independent of an electrically actuated armature (100). A second valve (200) is also disclosed which includes a poppet valve (202) having a cylindrical wall (206) which prevents the poppet valve from contacting the armature (100). A third valve, carried by the shock absorber piston (20) includes two axially extending passages one of which cooperates with a poppet valve (560) to increase fluid flow thereacross to reduce damping. Each valve can be actuated in accordance with the direction (sign) of a derived velocity signal.
