Abstract
A system for retrofitting a four-valve ABS system for traction slip control. According to the present invention, only the wheel brakes associated with the driven wheels are furnished with outlet valves apart from the prevailing electromagnetically operated inlet valves. A separating valve is additionally inserted into the brake line, and a self-priming return pump is used which additionally has a suction line to the brake line between the master cylinder and the separating valve. Preferably, the suction line is adapted to be closed by a hydraulic valve. The separating valve may also be replaced by a hydraulically operated valve version. The resulting advantage is that at most four additional solenoid valves are required for the entire brake system in order to realize traction slip control.
