Abstract:
A brake cylinder maintaining valve feeds brake pipe (BP) pressure through a choke to replenish and maintain brake cylinder (BC) pressure up, when the pressure in the brake cylinder drops below its original set pressure. In one embodiment, the brake cylinder maintaining valve may be a differential type valve having an input diaphragm and an output diaphragm having different surface areas.
