<p>A screw rotor assembly for a screw compressor or the like comprises a male screw rotor (1) and a female screw rotor (2) having rotor teeth each having a profile consisting of a plurality of special curves designed to reduce both the length of sealing line and the area of blow hole. The configurations of the male and female screw rotors (1,2) reduces the abrasion of the screw rotor assembly as well as the length of sealing line and the area of blow hole, so that the performance of the screw rotor assembly is improved. The length of sealing length and the area of blow hole in the screw rotor assembly of the present invention are about 10% and about 50%, respectively, of those of the conventional screw rotor assembly.</p> |
