  • Hydraulic clutch actuation system
    Patent number: 7571794
    Abstract: A hydraulic clutch actuation system having a hydraulic clutch control device which includes at least one clutch master cylinder that communicates via a pressure-medium line with a clutch slave cylinder used for actuating a clutch device, the pressure prevailing in the pressure-medium line being relievable via at least one emergency release valve device to permit disengagement of the clutch device in an emergency situation. The hydraulic clutch actuation system is distinguished in that the emergency release valve device has a seal-carrier device for a sealing element which is movable in response to an electromagnet out of an open position, in which a pressure-medium inlet is open, into a closed position in which the sealing element seals the pressure-medium inlet.
