Abstract
A relay valve for a vehicle brake system having an operating piston which moves in one direction in response to entry of a control pressure into one part of the valve and which by that movement causes an orifice to open whereby working pressure is allowed to enter another part of the valve and pass from there through various outlets. There are six outlets and each is connected to a respective brake assembly of the vehicle brake system. A damping piston is connected to the operating piston so as to move therewith and is subjected to the same pressure as that acting against one side of the operating piston but in a manner such as to provide resistance to movement of the operating piston in the aforementioned one direction.
