ABSTRACT:
A method for switching a pressure control device in which the pressure control device is switched only whenever the pressure of the pressure fluid prevailing on the master brake cylinder side of the pressure control device exceeds a predetermined switching pressure of the pressure control device. In this way, the switching frequency and hence wearing of the pressure control device are greatly reduced. The magnet coil is designed or excited such that it heats to a lesser extent upon its excitation. The method is especially suitable for pressure control devices that are provided in a hydraulic brake system for motor vehicles having an anti-skid system.
