Abstract

An electrically controlled shock absorber comprised of a piston element having a cavity in which a pair of sub-assemblies are contained. One sub-assembly comprises a pilot valve and its actuator and the other sub-assembly comprises a poppet valve. The two sub-assemblies have cooperating passages for defining the flow passage between the two chambers defined by the piston assembly. This construction permits the sub-assemblies to be tested before complete assembly and facilitates the manufacturing of the unit.
