Abstract

Un dispositivo de obturación mejorado utilizable, por ejemplo, en turbocompresores, que comprende dos miembros que pueden girar uno con relación a otro, uno de los cuales tiene una superficie cilíndrica y el otro de los cuales tiene una ranura anular, y un anillo de obturación situado en la ranura anular y que, se aplica a la superficie cilíndrica para separar dos áreas que pueden tener diferentes presiones de trabajo, caracterizado porque una de las paredes que se extiende radialmente del anillo de obturación incluye una parte achaflanada de tal manera que la dimensión axial de la superficie radialmente interna del anillo de obturación es menor que la dimensión axial de la superficie radialmente externa del, anillo de obturación, incluyendo la ranura anular una superficie en cuña de forma complementaria para cooperar con la superficie achaflanada del anillo de obturación.
