Gas compressor

A gas compressor belongs to the technical field of compressors. The device is characterized by comprising a driving device, air cylinders (8) and force transmission cylinders (4), the air cylinders (8) are symmetrically arranged on the two sides of the driving device, the force transmission cylinders (4) are arranged between the air cylinders (8) and the driving device, the driving device is connected with the bottoms of the air cylinders (8) on the corresponding sides through the force transmission cylinders (4), and the air cylinders (8) are vertically arranged and spliced with the driving device to form a U shape. And the two cylinders (8) alternately complete the strokes of compression and air intake. The two air cylinders of the gas compressor are oppositely arranged, the two air cylinders alternately complete compression and air inlet strokes, under the working load, due to the fact that air inlet and air outlet have pressure, force balance of the driving device is facilitated, the power of the driving
