Abstract

"BOMBA DE VáCUO". Uma bomba de vácuo do tipo de palheta rotativa, compreende um invólucro (50) que possui uma superfície de parede interna cilíndrica (52), uma primeira (54; 54') e uma segunda (56; 56') parede terminal em lados opostos do dito invólucro definindo uma cavidade de fluido no mesmo, orifícios de entrada (60) e de saída (62) de fluido em comunicação aberta com a dita cavidade de fluido, e um rotor (64; 64') se estendendo entre as ditas paredes terminais suportadas por um eixo de acionamento (70) para rotação em torno de um eixo geométrico excêntrico com a dita superfície de parede interna do invólucro, o dito rotor sendo fornecido com uma pluralidade de fendas substancialmente radiais se estendendo longitudinalmente (66) em torno da periferia do mesmo. Adicionalmente, são fornecidas uma pluralidade de palhetas (68), cada uma sendo suportada deslizantemente de modo radial dentro de uma respectiva das ditas fendas. A invenção compreende aquela pelo menos uma das ditas paredes terminais e o dito rotor compreende, em superfícies opostamente faceadas, um recesso anular (84, 86; 84', 84", 86', 86") e uma estria anular (88, 90; 88', 88", 90', 90") respectivamente, os ditos estria e recesso estando interengatados de modo a definir um espaço vazio radial (92, 96; 92', 96') e uma vedação axial (94, 98; 94', 98'), respectivamente, entre a dita pelo menos uma das ditas paredes terminais e o dito rotor, e que a dita combinação de rotor/eixo de acionamento é orientada axialmente.
