Abstract

A shock absorber of a monotube type utilizes a mechanically fixed base valve to regulate oil flow between the compression and compensation chambers, and a compressible bladder in the compensation chamber to allow volume compensation, which, together, eliminate the need for pressurized gas and a floating piston found in conventionally known monotube dampers.
