BRAKE CYLINDER RELEASE VALVES

摘要

A brake cylinder release valve for use between a brake cylinder and a fluid operable brake control valve such as a triple valve has a pressure input port communicating with output port for connection to a brake cylinder, the output port being connected via a restriction to one side of a pressure responsive member, to the other side of which the input port is connected, and a vent valve operable to vent the one side of the pressure responsive member which is thereby caused to move to operate a valve which vents the output port and closes the communication between the ports.
