Abstract

La presente invención se refiere a en un conjunto mejorado de sello del vástago de válvula, adaptado para asegurarse a una guía de válvula de un motor de combustión interna, donde este conjunto incluye una cubierta rígida, que define un eje longitudinal y que tiene una pared de extremo que contiene una primera abertura, un cuerpo de sello resiliente, anular, dispuesto dentro de la cubierta, el cuerpo tiene una segunda abertura, que define un labio anular interior, adaptado para suministrar un contacto sellador continuo con un vástago de válvula de movimiento recíproco, el cuerpo de sello además tiene una ranura circunferencial exterior, esta ranura define una pareja de paredes laterales, que se extienden radialmente, paralelas, la ranura además define un fondo, donde el cuerpo de sello está soportado en la primera abertura por la ranura circunferencial, la mejora comprende un espacio anular radial de flotación, definido por una cantidad predeterminada de calro radial entre la primera abertura y el fondo de la ranura, donde la circunferencia de la primera abertura es mayor que la circunferencia del fondo de la ranura; el claro radial predeterminado se adaptada para acomodar una cantidad específica de desplazamiento radial entre un vástago de válvula de movimiento recíproco y una guía de válvula, por lo cual se evita la distorsión del cuerpo de sello; el cuerpo de sello además comprende un miembro sellador de guía, que se extiende generalmente, en forma longitudinal, del cuerpo y adaptado para el contacto sellador con una superficie superior radial de una guía de válvula; y en que el miembro sellador está axialmente separado de la pared de extremo.
