Abstract

Enhancements to brake regulating valves for use in a pressurized fluid actuated dual brake system, comprising two pressurized fluid sources arranged to operate simultaneously with a first pressure line connecting a source to an actuator for a first brake and a second pressure line that connects the other pressure source to an actuator for a second brake, where the pressure regulating valve, which is inserted in practice, in the first pressure line to open and close the communication between the The first source and the first actuator comprise valve control spring means that normally keep the valve open and pressure sensitive means in the second pressure line, for closing the valve, the regulating valve comprising an axial valve closing element. movable in relation to a fixed annular valve seat characterized in that the element d The valve closure has an axially directed stem with which a separate but separate piston structure is coupled, normally pushed in practice towards an inoperative position free of said stem, but which reacts to a failure in the second pressure line to move axially. with the stem and thereby inducing a force that tends to open the closure element.
