In the oil refining process, a gas compressor is needed to compress natural gas into liquid for storage and transportation.

[0003] A Chinese patent with publication number CN103603785B discloses a gas compressor, including a piston-cylinder unit, an intake and exhaust valve assembly unit, an electromagnet unit and a position monitoring device control circuit unit. There are two electromagnet units, each of which includes an electromagnet; the piston-cylinder unit includes a cylinder, a piston and an inner air duct. The piston is a magnetic piston with different magnetic poles at both ends, which is placed in the cylinder. An intake hole is provided on the upper side of the cylinder wall. The inner air duct is arranged in the piston and is connected to the intake hole. Two electromagnet units are respectively arranged on both sides of the piston-cylinder unit.
