Abstract
A brake pressure booster and modulator for vehicle brake systems, in which a displaceable part is disposed in a pressure chamber that is acted upon by a master cylinder and communicates with the wheel brake cylinders, this part being in turn part of a permanent magnet, so that with increasing or decreasing pressure from the master brake cylinder, a transfer storage of potential energy takes place to a simultaneously increasing extent in one or the other direction by a magnetic operative connection with a second magnet. To effect pressure modulations when anti-skid functions are realized, the second permanent magnet is in operative magnetic communication with the first magnet and simultaneously is subjected to the movement of this second permanent magnet to open a relief pressure chamber while simultaneously closing the primary pressure chamber.
