Abstract

A brake valve device for three-circuit compressed air braking installations in motor vehicles having three independently controlled braking systems, for example for the front and rear wheels of the tractor and for the wheels of the saddle trailer, the pistons being used to regulate the braking pressure, as well as the intake and exhaust valves for the compressed air arranged, as is known in the two-circuit compressed air brake installations, inside of the valve housing, one after the other, in the actuation direction, the piston of the first brake circuit being mechanically influenced by a stepping member, and the piston of the second braking circuit, by the pressure of the first circuit, characterized in that the brake valve contains a one-piece relay piston, provided with an extension valve case itself known, which is mounted in the rear, in tandem manner, and which is chargeable by the pressure of the second brake circuit, through a bore of the box, itself known in two-circuit brake valves .
