Abstract
This invention relates to a rail vehicle brake system comprising an air brake cylinder (10, 11) with a piston (12) which is spring-biased for brake application on one side thereof, and a control system for selectively supplying pressurized air to said cylinder. On both sides of the piston (12) the air brake cylinder spaces (10, 11) are connected to a common control system (28, 31) for the supply of pressurized air thereto. The control system--by controlling the supply and discharge to and from the respective spaces--accomplishes a pressure differential between the spaces for service braking.
