In the combined pressure medium and spring loaded brake cylinder, a partition wall (1) divides the pressure medium brake cylinder (4) from the spring loaded brake cylinder (5). A piston rod (17) coupled to the piston (12) of the spring loaded brake cylinder (5) displaceably passes through a bore (18) in the partition wall (1). Two sealing rings (18' and 19), which seal off the piston rod (17) are located in the bore (18). A venting duct (20) to the atmosphere running in the partition wall (1) opens into that section (18a) of the bore (18) which is located between the sealing rings (18' and 19). In the event of leakages from the sealing rings (18', 19) an outflow of the compressed air passing through the leakage to the atmosphere is thereby achieved. <IMAGE> |
