When the piston starts to move from the cylinder cover, the working volume in the cylinder is gradually increased, at the moment, gas pushes away the air inlet valve along the air inlet pipe and enters the cylinder, and the air inlet valve is closed until the working volume is maximum; when the piston of the piston compressor moves reversely, the working volume in the cylinder is reduced, the gas pressure is increased, when the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve is opened, the gas is discharged out of the cylinder, and the exhaust valve is closed until the piston moves to the limit position. The above process repeats itself when the piston of the piston compressor is moved in reverse again. The eccentric wheel of the compressor rotates for a circle, the piston reciprocates once, and the processes of air inlet, compression and air exhaust are successively realized in the cylinder, namely a working cycle is completed.
