suction port and the discharge port are opened on equally sides of the cavity. Through the motion of a pair of
synchronous EPTs, the two rotors rotate in opposite instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to attain the
goal of blowing.
