A brake device of a rail vehicle includes at least one spring-loaded cylinder having a pressure port and at least one service brake cylinder having a pressure port configured to receive a service brake pressure. Further included is a control valve arrangement having at least three ports, wherein a first port is connected to the pressure port of the spring-loaded cylinder and the control valve arrangement is configured to connect the first port to one of the following: (1) a second port configured to receive a pressure derived from a first pressure reservoir; and (2) a third port.

Braking device for a rail vehicle

A brake device is provided with an actuator which is operated by a pressure medium, used to apply and release a vehicle brake, especially a brake of a rail vehicle, includes an actuating piston which defines two pressure chambers. One pressure chamber impinges upon the vehicle brake in an applied position and the other pressure chamber impinges upon the vehicle brake in a release position. The two pressure chambers are connected to each other by a line with an overflow valve which opens at least during part of the transition phases&#x2014;between the release position and open position&#x2014;and which is otherwise closed.
