ABSTRACT:
A shock absorber for use upon each corner of an automotive vehicle which includes a piston mounted upon a piston rod and appropriately disposed within a cylinder such that the piston separates the cylinder into a pair of operating chambers containing fluid. A damper valve which is electromagnetically operated is seated within the hollow interior of the piston rod. The damper valve includes a sleeve, spool, center pole piece and a coil which are retained within position within the interior of the piston rod by an appropriate adapter. The piston is seated upon an extension of the adapter and is held in place by a nut. Fluid within the chambers flows in a substantially unrestricted fashion through a flow path defined by the damper valve and is restricted in its flow by actuation of the coil to provide an electromagnetic field that moves the spool according to the signal applied.
