ABSTRACT:
A clutch system which provides an automatic coupling between an engine and a driven mechanism comprises a fluid-type servomotor connected to the clutch unit. The servomotor fluid passes through a circulation system comprising a progressively variable orifice, the cross-sectional area of which depends both on the position of the accelerator pedal and on the position of the clutch. A branch pipe placed in parallel with the circulation system is closed by a device which opens when the measured engine speed exceeds a predetermined threshold value. The branch pipe is provided with a second variable orifice which has a larger opening than the first and operates under the same conditions in order to increase the speed of clutch engagement.
