Abstract
In order to minimize the vacuum-dependent force component acting upon the valve body of a vacuum brake booster that is equipped with a pneumatically pressure-compensated control valve without requiring constructive modifications of the valve gear casing that accommodates the control valve, the invention includes a radially inner limit as well as the radially outer limit of a pressure compensation chamber in the valve gear casing, which is limited by the valve body, is formed by a guide part that guides the valve body.
