Abstract

A brake valve for a vacuum brake force booster, wherein the valve body (33) is movably located on the pedal piston (32). The valve body, through two springs (35, 39) is held in a central position in which the brake pedal and pedal piston may move the valve body between booster deactivated and deactivated positions. Two electromagnets (37, 40) are provided which draw the valve body (33) both in the actuating direction and against the actuating direction. In this manner, the valve (17) can be actuated independently of the pedal force, to either release or apply braking pressure as for automatic antislip or traction control.
