The technical characteristics of the invention is that: the rotor end face tooth profile contains four, five or six sections of tooth curves with the circular nature; when it has five sections, addendum circular arcs and dedendum circles are added to the addendum or the dedendum of the rotor; when it has six sections, both the addendum circular arcs and the dedendum circles are added to the addendum and the dedendum of the rotor at the same time, to form four different combination schemes; there are common tangents at the connection points of the two adjacent teeth forming curves, which has a smooth tooth-profile without cusp, a high-wearing feature, a long life of the rotor, a small leakage triangle, and a good sealing property.
