Master cylinder for hydraulically operated clutch or brake

摘要

The piston rod (5) of the master cylinder has a stop collar (8). The collar is supported on an end stop (7) on the end face of the housing (3) in the end position of the piston (4) corresponding to the disconnected position of the clutch. A spherical contact face is provided in the area of the end stop between the housing and stop collar. The faces are formed with convex and concave curvature so that they fit together.
