Abstract

The invention relates to a combined service brake and spring brake cylinder (1) for operating a service brake and a parking brake, comprising: A spring brake cylinder (4), a spring brake piston (10) and at least one accumulator spring (3) loading the spring brake piston (10) in a parking brake application direction, a service brake cylinder (6) and a service brake piston (18), the service brake cylinder (6) and the service brake piston (18) delimiting a service brake chamber (19) which can be pressurized and vented with a service brake pressure, the service brake cylinder (6), viewed radially, being arranged inside the spring brake cylinder (4). It is provided that the service brake piston (18) is displaceably guided directly on a radially inner circumferential surface of the service brake cylinder (6), or in that a diaphragm cooperating with the service brake piston (18) is fastened to the service brake cylinder (6) and/or to the spring brake cylinder (4).
