ABSTRACT:
A hydraulic shock absorber is disclosed of the type including a piston slidably mounted in a cylinder, with a metering sleeve defining variable area orifices utilized to produce variable resistance to movement of the piston in the cylinder. The shock absorber structure includes a piston having two piece construction with head and rod components brazed together into a unitary assembly, as well as a bearing sleeve retainer for the piston rod bearing formed in three separate pieces in order to provide relatively reduced manufacturing costs of these components over one piece construction.
