METHOD FOR REFUELING VEHICLES WITH COMPRESSED NATURAL GAS AND A SMALL-SIZED MEASURING AND DOCKING DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC B60S5/02 F17C5/06 

FIELD: gas industry.

SUBSTANCE: invention relates to the gas industry, specifically to the technology of fuel supply to motor vehicles (hereinafter referred to as MV) using compressed natural gas (hereinafter referred to as CNG) as motor fuel. To refuel NG, it is taken from the gas pipeline, drained, compressed to the required pressure, sent to pressure accumulators, from which CNG is fed into the high-pressure pipeline (hereinafter referred to as HPP). CNG is fed directly from the HPP pipeline through a flexible HPP sleeve into a small-sized measuring and docking device (hereinafter referred to as an automated gas nozzle). Operations for opening and closing the main tap in the automated gas nozzle, as well as operations for opening the drainage valve at the end of refueling before disconnecting the refueling path are carried out automatically. The measurement of the amount of CNG supplied is carried out in the section of the refueling path, which is part of the automated gas nozzle, after the main valve.

EFFECT: increase in the safety of technological equipment for filling MV and the accuracy of measuring the amount of CNG.
