AIR DISTRIBUTOR OF RAIL VEHICLE BRAKE Russian patent published in 2007 - IPC B60T15/18 

FIELD: railway transport; rolling stock brakes.

SUBSTANCE: proposed air distributor of brake has three-pressure member arranged in housing made of larger and smaller movable partitions interconnected by rod with possibility of interaction with two spring-loaded valves, pressure relay and discharge valve. Larger movable partition separates main-line chamber from working chamber. One of spring-loaded valves connects compressed air source with pressure relay through step and maximum filling member, and second spring-loaded valve can communicate main-line chamber with additional reduction member of brake main line and "softness" member of air distributor and working chamber charging member. Air distributor has plain and mountain duty device made in form of spring-loaded rod arranged in working chamber with possibility of interaction with larger movable partition. Rod passes through housing of three-pressure member, is sealed in housing and it projects into space which is coupled with main-line chamber through plain and mountain duties selector, and main-line chamber, in its turn, communicates with brake main line. To coupled working chamber with valve or is made with channel and holes. Check valve or valve coupled with movable partition is installed in channel communicating said space with main-line chamber. Movable partition separates two spaces, one of which is coupled with main-line chamber and the other, with said space.

EFFECT: simplified design and improved reliability of air distributor.
