Fan-shaped rotor set with balance positioning apertures |
| 摘要 |
A rotor set comprises a pair of engaging rotors disposed in a pump room of a housing rotating oppositely with identical speeds. Each rotor comprises a plurality of lobes, and each lobe has a fan-shaped end with a curved edge. The lobe generates an eccentric force to the rotor during the rotation to reduce mechanical consuming energy and save dynamic energy. Therefore, the rotors can achieve strong eccentric torque and self-vacuum effect with low dynamic energy. |
