AUTOMOBILE GAS FILLING COMPRESSOR PLANT Russian patent published in 1997 - IPC

FIELD: mechanical engineering; gas filling compressor plants. SUBSTANCE: plant has compressor with drive in form of internal combustion engine, device to take in gas from main line, preliminary gas cleaning device, gas pressure equalizing and gas flow forming device, gas flow rate meter, all installed on gas supply line between gas main line and compressor, water-and-oil separator with purging device installed on compressor pressure line, two adsorbers operating in turn, end filter, gas accumulator communicating with filling unit. Inlet space of internal combustion engine is placed in communication with line delivering gas into compressor through step down pressure regulator. Pressure-tight crankcase of compressor communicates with purging device of water-and-oil separator. Check valve and throttle are installed in parallel to each other in gas drying main line between water-and-oil separator and adsorbers. Adsorbers are connected with regeneration main line through check valves at one side and through self-adjusting unloading valve at other side. Outlet of unloading valve communicates with purging device of water-and-oil separator. EFFECT: enlarged operating capabilities, improved reliability. 5 cl, 8 dwg
