Abstract
An arrangement for mounting a brake power booster to a splash-board of a motor vehicle is proposed, which brake power booster is actuatable by means of an operating rod and is provided in a booster housing with at least a first evacuatable and a ventilatable second working chamber, the splash-board separating the motor vehicle's passenger compartment from a mounting compartment of the brake power booster, preferably the engine compartment. In order to eliminate the engine noises and the intake noises of the brake power booster, which have a disturbing effect, to a large extent by simultaneously sealing the passenger compartment, the present invention provides that the aeration of the second working chamber is effected via an aeration compartment communicating with the mounting compartment, said aeration compartment being confined by means of a protecting sleeve surrounding the booster housing and/or a control valve housing in part, said protecting sleeve being sealed both relative to the splash-board and relative to the operating rod.
