The compressor comprises a compressor body, a first air cylinder and a second air cylinder, the first air cylinder and the second air cylinder are arranged at the two ends of the compressor body, an air outlet is formed in the compressor body and communicated with an air inlet of the first air cylinder, and an exhaust port of the second air cylinder is communicated with an air inlet of the second air cylinder. When secondary compression is carried out, although the second filler exists between the second air cylinder and the machine body, the pressure of natural gas entering the second air cylinder is high, and the sealing mode of the second filler is dynamic sealing, so that part of natural gas in the second air cylinder leaks into the machine body, and the first sealing piece is arranged between the crankshaft and the machine body, so that the sealing effect is good. The part of natural gas entering the leakage is sealed in the machine body; the natural gas sealed in the machine body can be discharged to th
