After air inletting, the teeth peak of main and auxiliary rotors will be closed with the main case, during which time
the air will not flow out, that is to say, sealing process. Two rotors continue to do rotary motion, and its teeth peak will
coincide with teeth gutter at the suction end. The coinciding surface will gradually move to the exhausting end,
which is just the transporting process.
C. Compressing and Oil Spurting Process
The closed chamber composed of female rotorćmale rotor and main case continues to rotate with rotors and its
active line moves towards the exhausting edge, that is to say, the alveolus volume between the active line and air
outlet gradually decreases and the inner air is compressed to increase the pressure, meanwhile, lubricating oil
infuse the compressing chamber and mix the air.
D. Exhaust Process
When the meshing end face of rotors rotates communicates with the air outlet of the main case, the pressure of
the compressing air reach the highest, and the mixed air of compressed air and lubricating oil is discharged together.
Since the alveolus completely broke away from the air outlet, the volume of the alveolus is zero and the venting is
over, so it will enter the next new working process of air absorbing, compressing and venting.
