PNEUMATIC SYSTEM OF DIESEL LOCOMOTIVE COMPRESSOR PLANT Russian patent published in 2004 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to brake equipment of railway rolling stock and is designed to provide serviceability of pneumatic equipment in case of sharp drop of tightness of pneumatic system caused by disconnection of sections, opening of angle cock on feed main line or breakage of main line. Proposed pneumatic system of compressor plant of diesel locomotive contains compressor, check valve, main reservoirs, feed main line, angle cocks, pressure regulator and diesel locomotive control instruments with pneumatic drive. Novelty is that supply of outlet feed line from main reservoirs takes place through setter of installed tolerable pressure differential between main reservoirs and feed main line within the limits of which main reservoirs communicate with feed main line through connecting channel with throttle hole. Excess of pressure differential over preset value leads to overlapping of connecting channel. Communication of feed main line with main reservoirs is provided also through additional check valve. Pressure regulator is installed on outlet line of main reservoirs.

EFFECT: improved reliability of brake equipment.
