ABSTRACT:
A spring-loaded brake cylinder has a slideable braking piston one side of which is acted upon by a first spring in the braking direction and a second side acted upon by air under pressure in the release direction against the force of the spring. There is a releaseable mechanical coupling between the braking piston and a piston rod upon which is mounted a quick-acting piston. The quick-acting piston is actuated by air. The position of the braking piston controls a supply of air to and a discharge of air from the quick-acting piston so as to achieve pressurization and depressurization of the quick-acting piston.
