Abstract
A plunger arrangement ( ) for a braking servomotor that has an actuating piston to provide a force to activate a master cylinder. The plunger arrangement ( ) is located in a bore of a movable wall ( ) that separates the interior of the servomotor into a front chamber and rear chamber, The plunger arrangement ( ) is connected to a resiliently returned control rod ( ) and slides in bore as a function of an input force to define a braking application. The end of the plunger arrangement ( ) is slidingly fitted so as to bias a reaction disk of the actuating rod and transmit a reaction force to the control rod. The plunger arrangement ( ) includes a unidirectional clutch device ( ) comprising a key ( ) and a sleeve ( ) that are slidably mounted on a plunger ( ) such that when the control rod ( ) is actuated at a given speed the sleeve ( ) is locked in the bore of the movable wall ( ), independently of the control rod ( ), to maintain a braking application.
