Abstract
The combined service and spring-loaded brake cylinder has a service brake piston (11) and a tension piston (16) assigned to a storage spring (17). Between the tension piston, a wear stroke readjusting device with non-self-locking threading (44) is arranged. The threaded spindle (29) of the wear stroke adjusting device can be moved axially and held stationary via a conical coupling (40), which is also spring loaded in the closed direction and closes in the direction of the braking force output. There is also an annular piston (22), which can be moved into the release position by means of a second release pressure cycle at the tension piston (16) in order to move the piston. On an end section (25), which projects into free space, the tension piston (16) carries a nut (27) which can be pulled into its release position by screwing.
