The upper and lower ends of the valve cavity 7 are respectively connected to the intake channel 8 and the outlet channel 9. The intake channel 8 is connected to the first exhaust channel 5, and the outlet channel 9 is connected to the second exhaust channel 6. The compression assembly includes an eccentric shaft connected to the output shaft of the motor. Four mutually perpendicular compound piston mechanisms are provided on the eccentric shaft. When the eccentric shaft rotates, it drives the four compound piston mechanisms to move back and forth in the valve cavity 7, cooperating with the cylinder valve body assembly to realize the intake, compression and exhaust of the gas.
