Abstract
In a brake pressure regulator for a hydraulic brake system of automotive vehicles having an anti-locking control and/or a traction skid control and including a master cylinder and a hydraulic brake force booster, the actuating piston of the brake force booster along with a guiding member forms a modulator chamber. The pressure in the modulator chamber is varied by electromagnetically switchable blocking and passage valves thereby moving the actuating piston such that the force of the brake force booster is reduced and increased, respectively, thereby changing the pressures in the working chambers of the master cylinder. In this manner, in the control mode, the pressure in the wheel cylinders can be changed in accordance with a control algorithm to enable the brake pressure regulator to be operated in multiplex operation.
