Abstract

The shock absorber has an oil filled cylinder and a concentrically guided piston rod. The latter (1) passes through both cylinder (4) covers (2, 3). The cylinder (4) has annular narrowings (5, 6) at its ends. The piston rod (1) has two pistons (7, 8) whose dia. is smaller than that of the narrowings (5, 6). Both pistons have holes (9, 10) distributed in a circle, covered by rings (11, 12) under pressure of a spring (13).
