Abstract

A pneumatic brake booster for motor vehicles, comprises a booster housing, the interior of which is separated into a working chamber and a low-pressure chamber by an axially movable wall that can be supplied with a pneumatic differential pressure; a control housing; and a control valve which controls a differential pressure between the working chamber and the low-pressure chamber. The control valve controls an airflow between the working chamber and the low-pressure chamber or a surrounding atmosphere. The control valve has a plate valve and a valve piston, a seal region of which can be sealingly placed on the plate valve and which can be moved in a stroke direction R. A fine and low-noise metering of the brake force is achieved by providing a throttle point between the valve piston and the plate valve for throttling the airflow dependent on the stroke.
