Abstract
The present invention provides a method for designing single-lobe rotors of the present invention includes: curve portions of the of a curve E, an arc A, an arc B, an arc F, an arc C, an arc H, a straight line Y, and an arc G, wherein a center of the arc H located in line with a center of the arc C through a center of the defined rotor, and a center of the arc G is same as the center of the defined rotor wherein a radius of the arc G is defined between a center of the arc G and an end point of the arc H, from which two end points of the arc G is smoothly connected with the arc H and the arc C. The single-lobe rotors generated by the method is able to provide higher compression ratio and larger discharge capacity, secure a smooth process while working chamber undergoing compression and expansion, and reduce leakage.
