A spring brake actuator for a rail vehicle brake unit, comprising a cylinder and a rod shaped member. The actuator includes a cylinder-shaped housing, a piston with a piston rod and a spring intended to act in a brake applying direction. In order to obtain a truly modular system the actuator, as an integrated and self-contained unit, is arranged on the rod-shaped member of the brake unit. Its housing is attached to the brake unit cylinder. The actuator piston rod is tubular and slidable on the rod-shaped member. |
