The hydraulic control of a clutch, a module of attenuation of vibrations is a description of the decoupling and reduction of flow of the hydraulic fluid, which limits the speed of the pedal remontee

摘要

The present invention relates to a hydraulic control of a clutch in the attenuation module of the vibrations to a clutch pedal and of reduction of hydraulic fluid flow rate limiting the speed of ascent of the pedal. According to the invention, the attenuation module of the vibrations (5) is characterized in that it comprises, in particular, a movable element (14) in the form of a piston mounted slidably guided in the body (6) of the module (5), and the skirt (15) has its free end (25) which bears on an inner seat (26) in a released rapidly of the clutch pedal, to ensure the circulation of the hydraulic fluid under pressure towards the master - cylinder through one or more nozzles (27) in reduction of the flow rate of this fluid is defined between said free end and the seat (26) so as to limit the speed of ascent of the clutch pedal. The present invention finds application in the automotive field.
