A spring brake cylinder is provided for brake systems of vehicles. It includes a spring brake piston, which is arranged in a housing of the spring brake cylinder and can be actuated by at least one accumulator spring and separates a spring chamber containing the accumulator spring from a spring brake chamber of the spring brake cylinder that can be filled with air for release and can be vented of air for application. A circulation device is provided at least for venting the spring chamber directly into the atmosphere. The circulation device is configured as a diaphragm valve device having at least one elastically movable outlet diaphragm and at least one elastically movable inlet diaphragm. The inlet diaphragm and the outlet diaphragm are in a closed position in contact with an associated valve seat in the home position of the diaphragms and, when a pressure difference between the spring chamber and the atmosphere exceeding a minimum pressure value is present, the diaphragms are moved into an open position lifted from the valve seat in order to build up and reduce pressure in the spring chamber.
