Abstract

A clutch operating cylinder for a pressure-medium operated clutch which is arranged in the power train of a vehicle, is operable either by the clutch pedal or via a electronically controlled system, for example an anti-slip regulating system, has a housing divided into two chambers. In these chambers there are, apart from the release piston, two further pistons and a spring having a clutch characteristic, such that the electronic control is never able to clutch further than is specified by the clutch pedal, the clutch pedal bites when it is operated subsequent to electronically controlled engagement, and it is possible to use both the clutch pedal and the electronic control to declutch further when the clutch has only been partially declutched.
