Abstract
A vehicle load-controlled brake pressure regulating valve device which combines in one housing a unitary valve device performing dual functions of a vehicle load responsive control valve and of a relay valve, whereby the relay valve function is effected by pressure regulated by the vehicle load function. The dual purpose valve device functions as a unit in a single housing to thereby reduce manufacturing costs and installation space required.
