ABSTRACT:
A brake pressure limiting device is disclosed for use in a dual-circuit vehicle brake system. The device comprises two valve bodies arranged on a common axis. Each valve body has one inlet for connection with a master brake cylinder and at least one brake line outlet. The pressure at the outlet can be isolated from that at the inlet by a valve element which is axially movable within the valve body between an open and a closed position. Movement of both valve elements in the two valve bodies is controlled by a common actuating member which causes the valve elements to close when the pressures at the valve body inlets exceed a limiting value that is a function of the vehicle load.
