ABSTRACT:
A China Type 120 Brake Valve ECP Manifold includes a manifold block in fluid communication with at least one source of fluid pressure for communicating fluid pressure signals. A plurality of apertures formed through such manifold block allows fluid communication therethrough. The manifold block is engageable intermediate a pipe bracket and a service portion. A first passageway in such manifold block has fluid communication with a first aperture at a first end and has a second end adjacent an upper face of the manifold block. A second passageway in such manifold block has fluid communication with such service portion at a first end and has a second end adjacent an upper face of the manifold block. A third passageway in such manifold block has fluid communication with a second aperture at a first end and has a second end adjacent an upper face of such manifold block. A fourth passageway in such manifold block has fluid communication with such pipe bracket at a first end, is fluidly connected to such second and such third passageways, and has fluid connections adjacent an upper face of such manifold block. A control module engageable with the manifold block controls a plurality of valve devices, communicates with a car control device and fluid pressure sensing devices having fluid communication with at least one of such first, second, third, and fourth passageways. An exhaust passageway in such manifold block fluidly communicates with the fourth passageway, allowing fluid to exhaust to atmosphere.
