Hydraulic shock and vibration absorber

Abstract

Abstract 1. Hydraulically operating shock and vibration absorber, having a cylinder (1) closed at one end, surrounding a cylinder chamber (18), a piston (3) being slidably arranged in the cylinder (1) and provided with a nozzle-shaped control port (11), the piston being connected with a hollow piston rod (5) extending out of the open end of the cylinder (1), being provided with an equalizing chamber (12) and a compression chamber (6) being separated therefrom by a slidable separating piston (7) and being filled with a compressible agent, the cylinder chamber (18) and the equalizing chamber (12) being filled with a non-Newtonian damping fluid (8), being pressable from the cylinder chamber (18) via the control port (11) into the equalizing chamber (12) and vice versa when the shock absorber is under load, being characterized in that the control port (11) cooperates with a control element (15) having a varying cross-section and projecting into the control port, and the damping fluid (8) being a permanently plastic, homogeneous paste consisting of graphite, 0.1 to 8% by weight wetting agent, 0.1 to 10% by weight structural viscosity agent and to 10% by weight structural viscosity agent and 40 to 70% by weight polyglycolether, polyglycolester and/or a saturated aromatic or aliphatic carboxylic acid ester, in each case based on the total weight of the paste (8).
