Pneumatic servomotor for vehicle, has sensor immobilized between reaction plate and shroud, where predetermined gap separates front end of fitment from back end of sensor, in resting or non-braking position

摘要

The servomotor has a sensor (62) assembled on front end of a plunger. The plunger is associated to a control rod connected to a brake pedal. A fitment (66) is assembled between the sensor and a shroud (68) of back part of the plunger. The sensor is immovable between a reaction plate and a shroud (64), and a predetermined gap separates front end of the fitment from the back end of the sensor in resting or non-braking position.
