Abstract

The pneumatic brakes for the train incorporates precision pressure control valves in which the action of each valve is enhanced by having one of the valve seatings on a spherical bearing so that it automatically centralises with the valve element. A secure valve action is assured. The compact valve can be made from components with wide tolerances, while ensuring a leak-free operation. The seating of the spherical bearing is improved by gaskets in grooves in one of the spherical surfaces.
