International ClassG05G 001/14Foreign Application Priority Data1991-03-30 DEAbstractA device for operating a clutch, especially an automotive clutch, has a clutch lever with two end positions, a past-dead-center spring that acts on the clutch lever, which spring exerts a force on the clutch lever when the clutch lever is positioned between the dead-center position and an end position, such that the force is directed towards this end position, and finally, additional spring mechanisms, which act on the clutch lever to reduce the pedal force that must be applied to it between the end position corresponding to the engaged state of the clutch and the dead-center position. The additional spring mechanisms are designed and mounted in such a way that they are in actual working contact with the clutch lever only from the end position of the clutch lever corresponding to the engaged state of the clutch to the dead-center position of the clutch lever. | |
