ABSTRACT:
The invention relates to a hydraulically-operating shock and vibration absorber or damper, having a cylinder closed at one end, a piston slidable within the cylinder, the piston being connected with a hollow piston rod extending out of the open end of the cylinder. The interior of the piston rod and the cylinder define a chamber filled with an incompressible damping fluid. A space is defined in the piston rod separated from the chamber by a slidable separating piston. The space contains a compressible agent. The damping fluid is pressed out of one portion the chamber, through the control port, into another portion when the shock absorber is under load. The compressible damping agent is air or gas under normal pressure or else pressurized. The imcompressible damping fluid consists of a non-Newtonian, permanently plastic, homogeneous paste of high heat-conducting capacity composed of graphite, a wetting agent, intrinsically viscous agent and polyglycol ether, polyglycol ester and/or a saturated, aromatic or aliphatic ester of caboxylic acid. Into the opening of the piston, a control pin extends which increases or decreases the cross section of the opening when the piston moves in and out.
