Abstract

Un par de rotores (1, 2) helicoidales cooperantes, que comprende: un rotor (1) macho que tiene lóbulos (6) que se extienden helicoidalmente y ranuras intermedias, y un rotor (2) hembra que tiene lóbulos (7) que se extienden helicoidalmente y ranuras intermedias que engranan con los lóbulos (6) que se extienden helicoidalmente y las ranuras intermedias de dicho rotor (1) macho; en el que dicho rotor (1) macho tiene un radio exterior (RM) y un radio primitivo (RMP) que define un círculo primitivo (CMP); en el que cada lóbulo (6) del rotor (1) macho tiene en una sección predeterminada un flanco (14) de lóbulo delantero y un flanco (15) de lóbulo trasero que son sustancialmente convexos, siendo dicha sección predeterminada perpendicular a un eje (OM) del rotor (1) macho y a un eje (OF) del rotor (2) hembra; en el que cada lóbulo (7) del rotor (2) hembra tiene en una sección predeterminada un flanco (16) de lóbulo delantero y un flanco (17) de lóbulo trasero que son sustancialmente cóncavos; en el que cada lóbulo (6) del rotor (1) macho y cada lóbulo (7) del rotor (2) hembra tiene un perfil asimétrico en dicha sección predeterminada.
