Abstract
A brake device (10) includes a service brake valve (16) that produces an actuation-dependent pressure at a service brake valve outlet (20) when an operating means (18) is actuated. The brake device (10) includes a brake actuator (40) with a brake actuator inlet (39). The service brake valve outlet (20) is connected to the brake actuator inlet (39) via a pressure connection (14). The pressure connection (14) includes a directional control valve (24) and a check valve (30). The check valve (30) is bypassed in a first valve position of the directional control valve (24) to allow a fluid flow from the brake actuator inlet (39) to the service brake valve outlet (20) and a fluid flow through the check valve (30) from the brake actuator inlet (39) to the service brake valve outlet (20) is largely prevented in a second valve position of the directional control valve (24).
