ABSTRACT:
To make a sealing and guiding packet available to shock dampers in order to minimize or even entirely prevent the negative effects of the so-called stick-slip effect and thus permit greater riding comfort, a sealing and guiding packet is proposed which comprises the following features:a) A cylindrical gasket (6) surrounding an oscillating piston rod (10) and in contact with the latter, which has a first and a second end face (6a, 6b) and a cylindrical mantle surface (6c),b) a cylindrical elastomer element (7) surrounding the ring (6), which has two radially extending flanges (7a,7b), which thrust the ring (6) resiliently against the end faces, and which [elastomer element] has a radially extending third flange (7c) which biases the ring against the piston rod surface; as well asc) tightening elements (1; 1.1, 1.2, 1.3; 4) which in the working state keep the elastomer element (7) under bias both in the axial and in the radial direction.
