Abstract

PURPOSE: To provide a pressure control device having in its spring brake pressure control system a control valve which admits only the flow from an input port to an output port where the input pressure is larger than a predetermined level and yet communicates both of the ports to each other irrespective of the direction of the flow where the input pressure is smaller than the predetermined level.
