摘要
A hydraulic actuating device for actuation of clutches in a multi-clutch transmission for motor vehicles is disclosed, comprising a multi-circuit pump having an electric pump drive, at least two pressure circuits hydraulically connected with the pump, and a reservoir for hydraulic fluid, from which the fluid can be conveyed by the pump to the pressure circuits. In this regard, each pressure circuit starting from the pump comprises a non-return valve blocking in the direction of the pump, an electromagnetically actuable proportional throttle valve, by way of which the respective pressure circuit can be the subject of defined hydraulic relief in direction towards the reservoir, and at the outlet side a slave cylinder operatively connected with an associated clutch. The pump drive and the proportional throttle valves are electrically connected with a control unit, which co-ordinates the electrical activation of the pump drive and the proportional throttle valves.
