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.

Arrangement for mounting a brake power booster

A brake booster is easily fastened and free from play on the splash wall of an automotive vehicle. The guiding portion (10) of the booster housing (1) is provided with an annular groove (11) receiving a clamping ring (3) held on the splash wall (2) of the vehicle.

Arrangement for fastening a brake booster

A vacuum operated brake power booster including a retaining member for securing the edge bead of a moveable wall diaphragm of the booster to the booster control valve is disclosed. The booster includes a casing subdivided into two chambers by a moveable wall having a diaphragm which has an internal edge bead disposed in an annular groove in the control valve housing of the booster. An annular retention ring surrounds the bead of the diaphragm to the outside of the bead and radially retains the edge bead within the control valve housing groove.
