Abstract
The actuator comprises an electric motor, a reduction unit and a mechanism for converting the rotary movement driven by the motor into the reciprocating rectilinear motion of a driven member for transmitting its movement to a slider or plunger housed in a hydraulic cartridge for supplying a hydraulic actuator intended to operate the clutch of a motor vehicle. The motion conversion mechanism includes a cam-type operating member rotated by the motor through the reduction unit and acting on the driven member. The cam member has a profile comprising, in succession, a first portion designed to cause the disengagement of the clutch, a second portion designed to keep the clutch in the disengaged position, and a third portion designed to cause the engagement of the clutch.
