Abstract

The invention discloses a brake pressure regulator for anti-locking control and for traction skid control of automotive vehicles. The regulator comprises a master cylinder, a hydraulic brake force booster, an electronic controller which, based on sensor signals, at the output thereof, renders available variable signals according to a control algorithm to switch electromagnetic valves associated with the wheel cylinders, a pressure fluid source and a reservoir. A valve aggregate insures the adaptation of the pressure level from the pressure fluid source to the operating pressure desired for the TSC-mode and the ALC-mode. Moreover, the valve aggregate, with the brake applied, turns off the TSC-mode. The valve aggregate comprises at least one plunger/ball arrangement serving a the closing and/or control member. The advantages involved with this brake pressure regulator reside in the automatic pressure level regulation and the automatic turn-off of the TSC-mode. Moreover, the inlet and blocking valves otherwise required for the TSC-mode are eliminated. Advantageous use is made of ball/seat valves in the present invention.
