Title: Service and spring brake cylinders

Abstract: The cylinder of the combined service and spring brake comprises a service brake piston rod capable of being connected to a brake linkage by means of a clearance adjuster. It combines the releasing pistons (26, 50) of the spring brake and service brake cylinder (2) with its piston (11) and its piston rod (12) provided with a clearance adjuster (16), and at least a dividing attachment rotating between the spring piston (26) and the ring-shaped base (37), such as a spindle (55) simultaneously passing through an axial bore (56) provided in the ring-shaped base (37) and a conjugated blind bore (57) provided in the spring piston (26). The invention is applicable to combined spring cylinders using the service brake clearance adjuster.
