Abstract:
This invention relates to a brake booster (201) having an axis (X), comprising an enclosure divided into a front chamber (210) and a rear chamber (208) by a skirt (209) fastened to a piston (205) mounted so that it can slide in the axial direction (X), the booster comprising a nonreturn valve (225) to evacuate air from the front chamber when the pressure prevailing exceeds a certain reference value.According to this invention, this booster is characterized in that this nonreturn valve (225) is internal to the booster (201).
