ABSTRACT:
A direct acting hydraulic shock absorber having an improved assembly for mounting (1) one end of a fluid metering element with an end of the inner tubular member of the shock absorber adjacent the lower end closure fixed thereto and (2) the compression and replenishing valve mechanisms in hydraulic fluid flow control relation between the reservoir space and the compression space of the shock absorber. The assembly comprises a lower annular wall member mounted adjacent the lower end closure having a lower surface disposed in fluid communicating relation with the reservoir space, a central recess formed in an upper surface, and a pair of openings spaced from the recess extending from the upper surface to the lower surface, within which the replenishing valve mechanism and compression valve mechanism are mounted. A ball is fixed to one end of the fluid metering element and is seated within the recess. An upper annular wall member is peripherally fixed to the lower member and has (1) an opening in the central portion thereof for enabling the fluid metering element to extend therethrough; (2) an insert therein for grippingly engaging the ball to maintain the same within the recess; and (3) a series of openings between the periphery and the central portion thereof extending axially therethrough.
