Abstract

Improvements in brake pressure regulating valves, to be used in a double fluid pressure-actuated brake system, comprising two sources of pressurized fluid arranged to operate simultaneously, with a first pressure line connecting a source to a actuator for a first brake, and a second pressure line connecting the other source to an actuator for a second brake, where the pressure regulating valve, which is practically inserted in the first pressure line, to open and close communication between the first source and the first actuator, which comprises valve control spring means that normally keep the valve open and pressure sensitive means in the second pressure line to close the valve, the regulating valve comprising a axially displaceable valve closure element relative to a fixed annular valve seat, characterized by that the closing element is part of a self-metering valve and because the closing element has an axially directed stem that penetrates into a pressure space with an inlet to connect to the second pressure line, whereby the pressure in the Pressure space acts on the stem to induce an additional force that tends to close the closing element on the valve seat against the action of the valve control spring.
