Brake pressure booster in vehicle brake systems

A brake pressure booster for vehicle brake systems, which can also be used to realize anti-skid functions, including a displaceable element, in the form of a permanent magnet, disposed in a pressure chamber and acted upon indirectly by the master brake cylinder to apply pressure to a brake fluid communicating with a wheel brake cylinder. The pressure chamber is embodied such that with increasing or decreasing brake pressure of the master brake cylinder, a transfer storage of potential energy that simultaneously increases in one or the other direction takes place, whereby it becomes possible to raise or lower the pressure of the wheel brake cylinders in the manner of boosting. Furthermore, by providing an electrical exciter coil, influence can also be exerted upon the boosting action of the brake pressure booster by an additional influence upon a magnetic position in order to generate anti-skid functions.
