Abstract

See full text

A brake distributor valve for a Russian railway vehicle includes a body defining a brake pipe passageway configured to be in fluid communication with a brake pipe, a reservoir passageway configured to be in fluid communication with a reservoir, and a reference pressure passageway configured to be in fluid communication with a reference pressure source. The brake distributor valve includes a service accelerated release valve having a valve member with a first position where the brake pipe passageway is isolated from the reservoir passageway and a second position where the brake pipe passageway is in fluid communication with the reservoir passageway. The valve member is configured to supply pressure from the reservoir passageway to the brake pipe passageway during a brake release event, where the valve member is actuated between the first and second positions based on a pressure within the reference pressure passageway.
