A pneumatic brake servo for motor vehicles having a servo housing, the interior of which is divided into at least one working chamber and at least one vacuum chamber by at least one axially movable wall which can be loaded with a pneumatic differential pressure, having a control valve which controls the differential pressure and is arranged in a control housing for connecting the working chamber to the vacuum chamber or to atmosphere. The movable wall includes a diaphragm plate and a rolling diaphragm, and the working chamber is sealed by a sealing ring which bears against the control housing and which is clamped in the radial direction in relation to a longitudinal axis of the brake servo. An actively loaded area of the movable wall is reduced by division of the working chamber into a prechamber and a main chamber to avoid stick/slip effects and reduce disruptive noises.

Brake servo

The present invention relates to a vacuum brake force booster which includes a valve piston with a pedal push rod that is axially slidable in a vacuum housing, further including a control housing and a poppet valve connected to the valve piston, and an air filter. The air filter is arranged in the valve piston and forms, in conjunction with an associated valve piston sealing seat for the air filter abuttable thereon, a variable flow cross-section for the outside air that flows through the poppet valve.
