Abstract

La presente invención se refiere a mejoras en un sello compuesto para disponerlo en torno a un elemento circular que tenga un eje central, caracterizadas en que el sello comprende: un elemento sellador anular, primario, que tiene una dureza de 60 a 90 en la escala Shore A; un elemento sellador anular, secundario, que tiene una dureza de 90 a 125 en la escala Shore A; el elemento secundario es de sección radial en forma de U definida por piernas espaciadas en sentido radial y que se extienden en sentido axial conectadas por la parte curva que se extiende en sentido radial; las piernas del elemento secundario se pueden acoplar con el elemento circular y con la pared de un elemento o cilindro de soporte; las piernas del elemento secundario tienen caras de extremo axiales cónicas, inclinadas en sentido axial y radial hacia la curvatura del mismo; el elemento primario tiene un par de pestañas espaciadas en sentido radial con superficies inclinadas en sentido axial y radial complementarias y yuxtapuestas con las caras de extremo del elemento secundario para impedir la extrusión del elemento primario más allá de las piernas del elemento secundario.
