RAIL VEHICLE BRAKE AIR DISTRIBUTOR Russian patent published in 2007 - IPC B60T15/22 

FIELD: railway transport.

SUBSTANCE: proposed air distributor has two-pressure unit, hollow rod, brake main line additional reduction valve, inlet valve with seat, outlet valve and brake main line additional reduction limiter. Outlet valve of two-pressure unit has hollow shank with seal separating atmospheric space of two-pressure unit from space formed in two pressure unit and communicating through hole made in inlet valve. Travel of movable partition of brake main line additional reduction limiter at its release from braking position to beginning of communication of space of brake main line additional reduction limiter connected with brake chamber with space communicating with atmosphere through above-indicated channel main in brake main line additional reduction limiter is less that travel of said movable partition at its release from braking position to beginning of communication of space of brake main line additional reduction limiter constantly communicating with standby reservoir, with space constantly communicating with brake main line through channel of round spool of movable partition.

EFFECT: provision of required minimum pressure rise in brake main line to release brake and complete release of brake required by conditions of preset brake control process.
