摘要
The present invention relates to a brake force generator for a vehicle hydraulic brake system comprising a force input element that is connectable or connected to a brake pedal, a master cylinder, in which a primary piston is displaceably guided, wherein the primary piston with the master cylinder delimits a primary pressure chamber for generating a hydraulic brake pressure, and an actuating-force generating device for exerting an actuating force on the primary piston, wherein the actuating-force generating device comprises a control valve and a chamber arrangement, wherein the chamber arrangement is formed by a vacuum chamber and a working chamber, which is separated from the vacuum chamber by a movable wall and fluidically connectable by the control valve, and wherein the control valve comprises a control sleeve, which is displaceable relative to a valve element in accordance with a pedal actuation to achieve a pressure difference between the working chamber and the vacuum chamber that determines the actuating force. The invention provides that there is associated with the control valve a check sleeve, which is displaceable in accordance with specific operating conditions and the position of which may be used to influence the relative movement between control sleeve and valve element.
