ABSTRACT:
A braking system for a railway car in which a brake cylinder communicates with a compressed air line and atmosphere via a valve mechanism controlled by a pneumatic air distributor and an electropneumatic valve which communicate with the compressed air line. The valve mechanism communicates with the compressed air line via an auxiliary receiver and has two interconnected diaphragms of different areas spaced apart from each other. The diaphragms are also connected to the movable member of the valve mechanism during application of brakes and form chambers with the casing thereof, of which one chamber, which is defined by the greater diaphragm, communicates with the pneumatic air distributor, and the other chamber, which is defined by the smaller diaphragm, communicates with the electropneumatic valve connected to the auxiliary receiver. This construction of the braking system ensures reliable braking of both empty and loaded train.
