ABSTRACT:
A shock absorber which is inertia responsive in both compression and extension strokes to provide rapid flow in either direction responsive to rapid large changes in loading as caused by a bump or dip. The inertia responsive valving is located in the piston or the piston rod or both affording simple shock absorber body design and simple cooling. The inertia responsive valving members are longitudinally slidable and of substantially uniform cross section so as to be substantially immune to acceleration forces due to turns and are substantially insensitive to pressure changes.
