Abstract

This invention mainly relates to a pneumatic servomotor for an assisted braking, which reduces the noise in the passenger space to the minimum, while not requiring much room in the engine compartment, and it also relates to a motor vehicle equipped with such servomotor. A pneumatic servomotor (1) for an assisted braking, according to this invention, comprises an air-supply intake (25), opening into the engine compartment (35). Such a pneumatic servomotor (1) for an assisted braking is provided with a shell defining its outer wall (25), an area (27) of said shell defining an air-supply passage (29), preferably for atmospheric-pressure air, the passage inlet (57) opening into the engine compartment. In an advantageous manner, the area of the outer shell, which defines the passage, corresponds to the rear area, facing the dashboard cross-panel (33), which separates the engine compartment (35) from the passenger space (37). Preferably, the rear area corresponds to the wall of the rear chamber (7), capable of being filled with air at the desired pressure. Advantageously too, the air-supply passage (29) for the servomotor according to the present invention is in the shape of an angular sector which, in a preferred manner, is directed downwards so as to limit the ingress of solid particles and of liquids into the servomotor (1). The present invention concerns, more particularly, the motor car industry. And the present invention mainly applies to the design and manufacturing of braking systems.
