Abstract
A clutch system for closing and interrupting a force flow includes a clutch actuator that can have a pressure medium applied thereto, a first electrically actuatable valve device and a second electrically actuatable valve device. Pressure medium can be fed into a switching chamber of the clutch actuator by the first valve device for building up pressure, and pressure medium can be discharged again by the second valve device for releasing pressure. The clutch system interrupts or closes the force flow at a pressure P≧Pd in the switching chamber. A method for operating the clutch system for closing and interrupting a force flow prevents a subsequent pressure buildup in the switching chamber sufficient for actuating the clutch system if the first valve device and the second valve device malfunction.
