VEHICLE AIR SUPPLY SYSTEM Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: system contains compressor with drive motor controlled by pressure relay, two adsorbers, outlet of each adsorber being coupled with being coupled with compressor through cutoff valve, blowing valve dry air main line, and control unit. System is made for delivery of hot air from compressor into one of adsorbers at each cycle of system operation. Adsorbers are coupled through group of reservoirs used for natural cooling of air and separator-accumulator with blowing valve. Other cutoff valve is installed in lower part of each adsorber through which inner space of adsorber communicates with dry air main line. EFFECT: reduced power consumption at air drying owing to preventing air losses for regeneration of adsorbent. 1 dwg
