Railway car pneumatic braking system - includes valve controlled by air distributor and electro-pneumatic communicating with compressed air line

摘要

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. One chamber defined-by the greater diaphragm communicates with the pneumatic air distributor, and the other chamber, is defined by the smaller diaphragm, communicates with the electropneumatic valve connected to the auxiliary receiver. This construction ensures reliable braking of both empty and loaded train.
