Abstract
A vehicular shock absorber is disclosed and includes a two-piece piston head, one piece being the mirror image of the other, mated by a pin. The piston head defines a series of passages. Identical valve assemblies are positioned in the passages so as to allow passage, under pressure, of hydraulic fluid in both directions between a compression chamber and a recoil chamber. Each valve assembly includes a spring clip, partially encompassing the valve bias spring so as to limit potentially damaging compression thereof. The shock absorber further includes a compression head assembly, providing fluid communication between the compression chamber, and a reservoir chamber, and a cylinder head assembly which, in part, seals about and maintains the piston rod.
