Abstract

resumo "par de rotores de parafuso de cooperação? a presente invenção se refere a um par de rotores de parafuso de cooperação que compreende um rotor macho e um rotor fêmea. o rotor macho possui lóbulos que se estendem em espiral e sulcos intermediários, e o rotor fêmea possui lóbulos que se estendem em espiral e sulcos intermediários que são configurados para intercalar com os lóbulos que se estendem em espiral e os sulcos intermediários do rotor macho. o rotor fêmea tem um raio de altura que define um círculo de altura. cada sulco do rotor fêmea possui um primeiro flanco que compreende pelo menos três seções côncavas. uma primeira seção compreende, ou está disposta imediatamente adjacente, o ponto radialmente mais interno do dito sulco. uma segunda seção é moldada como um arco circular com um raio que tem seu centro situado fora do círculo de altura. uma terceira seção é moldada como um arco circular com um raio que tem seu centro situado fora do círculo de altura. o raio da terceira seção é maior do que o raio da segunda seção, que é maior do que a distância radial entre o círculo de altura e o ponto radialmente mais interno do dito sulco.
