Multi-circuit pressure medium brake system

摘要

A multi-circuit pressure medium brake system in which a pressure control valve is used which can be triggered in a multi-circuit manner. One of the controls is effected electrically and generally advances ahead of a pressure-medium control, so that when the system is functioning properly, the pressure-medium control remains without effect. Various modifications for the pressure control valve have been set forth and a plurality of combinations of switching members for meeting various pressure regulating conditions have been set forth. The multi-circuit pressure medium brake system is preferably applicable to motor vehicles.
