Abstract
An improved automotive shock absorber assembly comprises a housing containing a fluid, a shaft extending axially into the housing, a piston head connected to the shaft within the housing, a volute spring cooperating with the shaft and piston head and adapted to compress in the fluid when the shaft is subjected to axial loads, means for sealing the housing to prevent the leakage of liquid therefrom, and means for maintaining the shaft in axial alignment within the housing when the shaft is subjected to off-axis loads.
