IMPROVEMENTS IN THE DESIGN OF AIR BRAKE CONTROL VALVES

The paper traces the development of the air brake control valve from its earliest ancestor, the original triple valve invented by George Westinghouse, up until the present day. Emphasis is placed on the way in which constructional techniques evolved, developments on both sides of the Atlantic being considered. The desire for improved performance, reduced costs and an extended maintenance period is shown to be the driving force towards change, which is inevitable once the required skills and techniques become available. The authors show how worthwhile improvements are still feasible and introduce a new design of control valve based on constructional techniques intended to realize these.
