Abstract
A declutching device comprises an hydraulic actuator, a preloading spring for permanently biassing the movable member of the actuator towards its retracted position with respect to the fixed member of the actuator, and a retaining ball which is adapted to retain the movable member in a withdrawn position with respect to the fixed member during and prior to assembly. A feeler projects outwardly from the hydraulic actuator, so as to be displaced by the clutch while relative axial movement of the clutch and declutching device towards each other is taking place during assembly. The feeler is mounted for movement between a fitting position in which it allows the retaining ball to carry out its above mentioned function, and an operating position in which the retaining ball is no longer effective. The invention is applicable to clutches of the pull-off type, especially for motor vehicles.
