Abstract

1.Obturador de fluido rotativo, para evitar la fuga de fluido entre dos elementos coaxiales de rotación relativa, del tipo que comprende un anillo obturador flexible circular, situado libremente para flotar de una forma prácticamente coaxial entre superficies contrarias axialmente opuestas de los elementos de rotación relativa, teniendo el anillo obturador un par de labios de estanquidad divergente radialmente hacia fuera, dirigidos axialmente en sentidos opuestos que presentan caras anulares de contacto para apoyarse reslientemente contra las superficies contrarias, respectivamente, de modo que el anillo obturador sea impulsado en rotación por fricción por uno u otro de los elementos en su rotación relativa, teniendo los labios de estanquidad, entre sí, un dispositivo de resorte que actúa radialmente para someter indirectamente a carga a las caras de contacto resilientemente contra las superficies contrarias, caracterizado porque tiene previsto un anillo rígido de retención del muelle, quepermite, pero limita, la dilatación centrífuga del dispositivo de resorte y retiene el dispositivo de resorte en una relación de carga con los labios de estanquidad. 2.Obturador según la reivindicación 1, caracterizado porque el anillo de retención del resorte es un anillo con pestaña metálico o de plástico, de sección prácticamente en L, que tiene una pestaña prácticamente radial que descansa contra una cara interior opuesta de una labio de estanquidad, pero que no se sujeta a la misma, y una pestaña prácticamente axial pero divergente hacia fuera, o acampanada, que rodea al dispositivo de resorte, con holgura en condiciones estáticas o de baja velocidad, pero que a gran velocidad se pone en contacto con el dispositivo de resorte, limitando la dilatación centrífuga y transmitiendo su carga al labio de estanquidad contra el cual descansa su pestaña radial. 3.Obturador según la reivindicación 2, caracterizado porque la pestaña radial del anillo de retención del resorte se configura para adaptarse y cubrir la mayor parte de la cara interior de un labio de estanquidad. 4.Obturador de fluido rotativo.
