ADAPTER ASSEMBLY FOR BRAKING SYSTEM

Abstract:

An adapter assembly for an electronically controlled pneumatic (ECP) manifold system includes a housing having a mounting face that includes a plurality of ports. The housing also has a brake cylinder passageway, a reservoir passageway, and a brake cylinder exhaust passageway that are in fluid communication with the ports. The adapter assembly also includes an adapter valve configured to be in fluid communication with the brake cylinder passageway, the reservoir passageway, and the brake cylinder exhaust passageway. The adapter valve has a first position where the brake cylinder passageway and the reservoir passageway are in fluid communication while the brake cylinder passageway is isolated from the brake cylinder exhaust passageway. The adapter valve also has a second position where the brake cylinder passageway is isolated from the reservoir passageway while the brake cylinder passageway is in fluid communication with the brake cylinder exhaust passageway.
