METHOD OF FILLING VEHICLES WITH COMPRESSED NATURAL GAS Russian patent published in 2002 - IPC

FIELD: transport engineering; vehicle servicing. SUBSTANCE: proposed method comes to arrival of mobile gas filling truck with filling column at site of filling of vehicles operating on compressed natural gas and filling the vehicles with compressed natural gas through filling column using booster compressor mounted on separate frame equipped with wheeled running gear and telescopic turnable supports. Frame carries also receiver, additional filling column and internal combustion engine operating on compressed natural gas and serving as drive for booster compressor provided with at least two intake and two outlet manifolds with units for connecting movable gas filling trucks with compressorless takeoff of compressed natural gas. Intake and outlet manifolds and units coupling movable gas filling trucks with compressorless takeoff of compressed natural gas to booster compressor are provided with shutoff valves to regulate delivery of compressed natural gas to filling columns and to receiver of booster compressor and to transfer compressed natural gas between sections of vessels of one gas filling truck or different gas filling trucks. EFFECT: increased efficiency. 3 cl
