ABSTRACT:
A hydraulic twin-pipe shock absorber for horizontal use and which is particularly suitable for use with rail vehicles. The shock absorber includes a cylindrical housing with a fluid-filled working cylinder provided inside the housing. A piston is displaceable in the working cylinder and is connected to a clearance between the housing and the working cylinder. The construction of the shock absorber removes air and foam from the working cylinder so that pressure builds up evenly and uniformly.
