Abstract: A construction and fabrication process for a two piece vacuum brake power booster housing is described which eliminates the surface tensions which are caused by forming during assembly to prevent damage to a protective surface finish. Localized radially weakened zones are each formed by two opposing tongues created by circumferential and axial slots which tongues in the assembled condition of the housing engage behind an outwardly and reversely formed rim (3) of the other housing half (1).

Abstract: A vacuum brake power booster, in particular for motor vehicles, which includes a poppet valve (12) sealing two valve seats (18, 19) and which is axially deformable within the area of a rolling fold (15) also includes an annular part which is either mounted on the outside of the rolling fold (15) in a form-fit manner or arranged inside the elastic material (24) of the poppet valve (12). This annular part prevents the rolling fold (15) from being blown up outwardly due to the pressure differential prevailing between its two sides so that it will be possible to reduce the return force and thus also the response force.

Abstract: In order to simply and economically fix to an internal-thread coupling (12) a pipeline (17) furnished with two slidable external-thread connections (15, 18), the invention contemplates fabricating the two external-thread connections (15, 18) together in the shape of one part only. At a predetermined screw-in torque, one external-thread connection (15) is torn off and as a result one pipeline end (16) is safely retained in the internal-thread coupling (12). The second external-thread connection (18) may be slid to the second end (21) of the pipeline and can fix the latter to a further internal-thread connection. The fixing means and methods contemplated by the invention are automation compatible and, upon fixing, protect the pipeline from being detached from the coupling through faulty handling.

Abstract: A process for the precise adjustment of the lost travel of a piston in a master cylinder. Master cylinders typically include a number of components in spatial series arrangement, with all components having individual tolerances. The individual tolerances regarding the lost travel of the piston or pistons, can combine additively in the master cylinder. The resulting lost travel, hence, is relatively large and varies with individual master cylinders. The process provides that the lost travel of the piston or pistons in the master cylinder can be precisely adjusted and, hence, can be kept very low. The position of the piston or pistons is measured in the condition in which they just seal the associated equilibrium ports. Subsequently, the position of the pistons is calculated in consideration of the desired lost travels and, by adjustment of the force planes acting on the desired point, the resting position of the piston and pistons, respectively, is fixed to the desired distance.

Abstract: As an improvement on conventional brake systems of the type having a multiple-chamber vacuum brake force booster, a modification is disclosed to the effect that, in the brake releasing position, there is a pressure medium communication between a booster chamber and a simulator chamber. A modulator chamber requires only one external connection, thereby substantially simplifying the construction of the brake force booster and readily permitting an extension of the system's use to include traction slip control.

Abstract: In order to enable a brake booster to operate both with a pressure above atmospheric and with atmospheric pressure without any negative mutual influences of the two energy types and without any change in the responding behavior of the device in case of failure of either energy type, the invention provides a pneumatic system which, during the operation of the brake booster with pressure above atmospheric, causes a force constituent to become active so as to counteract the forces caused by the increased pressure difference and acting on the control valve piston as well as on the control valve housing.

Abstract: In a power brake booster for an automotive vehicle, with a housing (1, 2) subdivided into two compartments by a partition wall (41), the compartment close to the brake pedal contains a working chamber (25) and a vacuum chamber (33), while the compartment close to the master cylinder contains a working chamber (24) and a vacuum chamber (32), with a longitudinally slidable control housing (4) with valve device (8, 37, 38) being sealably held and guided in a central opening of the partition wall (41), the said control housing incorporating a longitudinal channel, for instance on annular gap (21) which, on the one hand, is via an opening or bore (26) in communication with the one working chamber (24), while, on the other hand, it terminates into a chamber, for example an annular chamber (20), which is connected to the valve chamber (42) behind the valve device (8, 37, 38) and which is connected to the other working chamber (25) via a cross bore (39).

Abstract: 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.

Abstract: A vacuum-operated brake power booster is provided having a movable wall which is sealed off relative to the vacuum housing and a control valve body which is slidable jointly with the movable wall. A hollow cylinder-shaped expanded plastic ring is arranged in the annular clearance between the neck portion of the pedal side housing shell and the collar of the diaphragm, which collar sealingly surrounds the control valve body. The expanded plastic ring effects the air flow during brake operation such that the air flow, enters the annular clearance through the duct extending in a radial direction within the control valve body and is suitably deflected and cushioned so that no noises arise at this point. In the same manner and simultaneously, vibrations, especially those of the neck portion of the housing shell of the vacuum housing, are suppressed, since the expanded plastic ring adheres to the inside wall of the housing shell.

Abstract: In a vacuum-operated brake power booster, a transverse member is provided which confines the axial movability of the control piston relative to the control housing. The transverse member abuts against a bead of a rubber-elastic material, the bead forming part of the slide-guide ring sealing the booster housing relative to the control housing. The tranverse member is formed of a substantially U-shaped sheet-metal blank, with both free ends of the fork arms extending parallel to two limbs of the member. The arms are provided with hook-shaped tabs which are bendable around a pin forming part of the control housing for the purpose of fixing the transverse member in its aperture in the control housing. In order to enable a proper and easy bending of the tabs during assembly, notches are provided at the radially outside small faces or edges of the two fork arms.

Abstract: Differential pressure brake boosters are known having a reinforcement tube extending axially through the low-pressure casing with its ends fastened to both end surfaces of the casing. A mechanically actuated control valve for connecting the working chamber to the low-pressure chamber or to atmosphere is axially movable in the reinforcement tube. A sleeve surrounding a master cylinder piston push rod has radial ribs extending through longitudinal slots of the reinforcement tube to connect the push rod to the movable wall. These ribs are subjected to a high bending stress. According to the present invention the radial ribs are constructed as flat tongues disposed in a common plane, the tongues being engaged on a side thereof adjacent the low-pressure chamber by an outwardly angled collar of an extension of the housing of the control valve.
