Air machine working process is divided into suction, its steam, pressure and sea over, exhaust this process. First of all, in the process of limiting the air inlet: when the groove mounted to the air inlet, the outside world air that is inhaled, along the flow, the main rat mounted son of the cause of the river, when the air filled with the whole tooth groove on the rotor's air intake team often re-turned away from the casing of the air intake, in the tooth groove air that is closed, this time the air in the tooth groove closed and no longer outflow.

Then is the exhaust process.

The main country loads the son line to continue to load the action, when the medicine son of the joint weight turn to use and the machine ho non-gas communication, the pressure of the gas to give, until the value and the step of the joint repair to the exhaust surface, when the goods and the step of the gas in the service to please you to close, you close to the surface level gradually to the gas to please the action, this did not have two loads of the son of the joint surface and the casing of the exhaust port of the space is zero, that is, to complete the process of exhausting the gas.

Next is the air compressor compression and oil injection process.

In the process of conveying, the surface gradually move to the exhaust lies to do that is to say, the surface and the exhaust port with the teeth of the enquiry gradually small, the bubble of the gas inside the teeth gradually be music, the pressure office to raise, this (pressure first process. At the same time, the oil is sprayed into the pressure maintenance chamber and the gas in the chamber due to the force of the United States, and the pressure is increased.

Finally, the exhaust process of the air compressor.

When the rotor's end face to turn to and casing exhaust through, to pressure the gas pressure of the highest pressure of the pressure of the gas began to discharge, until the baked with the surface of the more to my gas surface, to the two mounted letters of the surface and the casing of the non-air port this tooth empty for zero, that complete the process of gas, in the same just the surface of the rotor and the casing of the air inlet between the length of the tooth groove and the maximum length of the suction process is again in progress.
