Abstract

1.Un dispositivo de rotor para un compresor centrífugo, que comprende una parte de cubo destinada a ser montada sobre un árbol de accionamiento giratorio y conectada de modo enterizo a una parte de disco coaxial que se encuentra en un plano perpendicular al eje de rotación del cubo, y una pluralidad de álabes montados sobre una cara frontal de las partes de disco y cubo para impartir al aire u otros gases alimentados al rotor un movimiento generalmente en sentido radial hacia afuera con relación a la parte de disco, siendo los álabes (a) verdaderamente radiales, (b) rectos y retraídos o en flecha con relación a una dirección radial, o (c) curvos y retraídos o en flecha con relación a una dirección axial, caracterizado porque los álabes están modificados de tal manera que, en el caso (a), los álabes que se extienden radialmente están provistos de partes de punta retraídas o en flecha, en el caso (b) los álabes retraídos están provistos de partes de punta adicionalmente retraídos, y en el caso (c) los álabes curvos retraídos están previstos de partes de punta adicionalmente retraídas, cuya curvatura aumenta con relación a la curvatura d ela parte principal del álabe, siendo tal la curva de dicha parte de punta retraída en el caso (a) y de dicha parte de punta retraída adicional en los casos (b y c), que define la superficie frontal del álabe, que el radio de la curva disminuye uniformemente hacia el extremo radialmente exterior del álabe, con lo que el radio mínimo de dicha curva aparece en el extremo radialmente exterior del álabe. 2.Un dispositivo de rotor para un compresor centrífugo.
