Abstract

Un sello para árbol giratorio bidireccional para sellarse entre un par de miembros relativamente giratorios uno de los cuales gira alrededor de un eje y que dispone de una orilla de sellado anular que se extiende radialmente definida entre una primera y segunda superficies troncocónicas convergentes que se extienden alrededor de un eje común; una pluralidad de proyecciones de bombeo hidrodinámicas que se extienden desde una de las superficies teniendo cada proyección de bombeo una superficie de bombeo primaria que se extiende por lo general axialmente desde la orilla de sellado y radialmente hacia afuera de la segunda superficie y que tiene una superficie de regreso que se extiende radialmente hacia afuera desde la segunda superficie para definir la extremidad trasera de la proyección de bombeo, caracterizado porque cada proyección de bombeo incluye una superficie de bombeo secundaria que se extiende axialmente entre la superficie de bombeo primaria y la superficie de regreso y radialmentehacia afuera desde la superficie de bombeo primaria a un ángulo poco profundo (A) con relación a l a superficie de bombeo primaria.
