Zero clearance screw rotor profiles are modified by determining clearance requirements at spaced points on the profiles and varying the clearance distribution between adjacent points using a non-linear distribution. This results in a reduced total clearance and hence a reduced leakage. Additionally, when the clearances are put in the rotors, zero clearance is maintained between the rotors in the contact band which is maintained near the pitch circle. <IMAGE> |
