Adapter assembly for braking system

An assembly comprising:

• a manifold assembly comprising:
• an electric manifold assembly having a mode where the electric manifold assembly is controlled electrically;
• and
• an adapter assembly comprising:
• a housing having a mounting face coupled to the manifold assembly, the mounting face including a plurality of ports, the housing including a brake cylinder passageway, a reservoir passageway, and a brake cylinder exhaust passageway that are in fluid communication with the ports;
• and
• an adapter valve contained within the housing, and configured to be in fluid communication with the brake cylinder passageway, the reservoir passageway, and the brake cylinder exhaust passageway, the adapter valve having 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 and 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.

An ECP overlay and adapter assembly for a W-type triple valve system, the assembly comprising:

• an ECP overlay manifold assembly comprising:
• a manifold body comprising a pipe bracket face configured to engage a face of a pipe bracket of a railway brake system, a valve face configured to engage a face of a W-type triple valve of a railway brake system, and an electric manifold face;
• and
• an electric manifold assembly engaged with the electric manifold face of the manifold body, the electric manifold assembly having an ECP mode where the electric manifold assembly is configured to allow electronic control of a brake cylinder of a railway brake system;
• and
• an ECP adapter assembly comprising:
• a housing having a mounting face engaged with the valve face of the manifold body, the mounting face defines an auxiliary reservoir port, an accelerated release reservoir port, a brake cylinder port, a brake pipe port, and a brake cylinder exhaust port, the housing defining a brake cylinder passageway in fluid communication with the brake cylinder port, a brake pipe passageway in fluid communication with the brake pipe port, a combined reservoir passageway in fluid communication with the auxiliary reservoir port and the accelerated release reservoir port, and a brake cylinder exhaust passageway in fluid communication with the brake cylinder exhaust port;
• a charging valve in fluid communication with the brake pipe passageway and the combined reservoir passageway, the charging valve configured to prevent a backflow of air from the combined reservoir passageway to the brake pipe passageway;
• and
• an adapter valve contained within the housing, and in fluid communication with the brake pipe passageway, the brake cylinder passageway, the combined reservoir passageway, and the brake cylinder exhaust passageway, the adapter valve having a first position where the brake cylinder passageway and the combined reservoir passageway are in fluid communication while the brake cylinder passageway is isolated from the brake cylinder exhaust passageway, and a second position where the brake cylinder passageway is isolated from the combined reservoir passageway while the brake cylinder passageway is in fluid communication with the brake cylinder exhaust passageway.
