The functioning basic principle of the three-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. By means of the motion of a pair of
synchronous EPTs, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gasoline in the chamber is pushed to accomplish the
objective of blowing.
