Abstract
A pneumatic servomotor for an assisted braking of a motor vehicle having a unidirectional clutch device ( ). The clutch device ( ) has a coaxial sleeve ( ) that slides on a plunger ( ), and a substantially ring-shaped key ( ) that is arranged with a given clearance around the sleeve ( ) and driven by a moving piston ( ). When an input force is applied at a determined speed onto a control rod ( ) that is integral with the plunger ( ), the key ( ) rocks and locks a finger ( ) that biases the piston ( ) with respect to the sleeve ( ) in an axial position. The key ( ) includes a peg ( ) for axial indexing of the locking position of the sleeve ( ).
