Abstract

Un miembro de sello elastomérico anular incluye un reborde de sello estático y una serie de proyecciones orientadas al lubricante. Cada proyeccion tiene una superficie frontal convexa que proporciona dos caras de bombeo orientadas de manera opuesta y una superficie trasera angulada que intersecta la superficie frontal a un ángulo agudo de manera de formar un borde delantero agudo. El borde delantero agudo en cada proyeccion tiene un espacio libre radial relativamente pequeño con respecto a la superficie cilíndrica que va a sellar. Este espacio libre pequeño permite que las proyecciones ejerzan fuerzas de bombeo sobre el lubricante proximo a la superficie cilíndrica.
