ABSTRACT:
A clutch system has a clutch device, an actuating device for the hydraulic actuation of the clutch device, and a hydraulic system. The hydraulic system includes a master cylinder that is actuated by the actuating device, a slave cylinder for actuating the clutch device fluidically connected with the master cylinder through a pressure line. A first branch line is connected to the pressure space of the master cylinder or between the pressure spaces of the master cylinder and slave cylinder. The first branch line is also connected to a compensating tank volume. A second branch line is connected to the pressure space of the slave cylinder or arranged between the pressure spaces of the master and slave cylinders. The second branch line is also connected to the compensating tank volume. A device is disposed to blocking the second branch line during an actuation of the clutch device by way of the actuating device. This provides for an inherently safe, self-ventilating hydraulic system.
