The invention relates to preparation of natural gas for its following transfer under pressure to fuel tank of a vehicle. A method for gas compression for car filling consists in alternating gas supply to two vertical compression vessels, its compression and displacement to high-pressure vessels by means of filling compression vessels with liquid under pressure with use of hydraulic drive. According to the invention each cycle of compression and displacement of gas from compression vessels is performed to complete filling of those with liquid that is placed to compression vessels with alternation pressing from one compression vessel to another one. The compression vessels 1 and 2 are equipped with shutoff devices 3 connected to sensors 4 of complete filling vessels 1 and 2 with liquid 30 and installed in mouths of compression vessels 1 and 2. |
