Piston-cylinder unit for friction brake has piston with seal holder on which seal is arranged and that is radially movable with at most limited axial movement with piston

摘要

The piston-cylinder unit has a piston (22) that is axially movable in a cylinder (20) and a device for loading the piston in the transverse direction. The piston has a seal holder (36) on which the seal (40) is arranged and that is radially movable with at most limited axial movement with the piston. The piston can have two seals that seal it in the cylinder. An independent claim is also included for the following: (a) a friction brake.
