Abstract

La presente invención se refiere a un sellado para émbolo o vástago, que comprende un anillo recolector de aceite, situado dentro de una primera ranura, radialmente abierta, hacia el componente de máquina que se mueve relativamente, constando el anillo de un material de PFTE, y que aprieta mediante un anillo en O, situado en la base de la primera ranura, hecho de material elástico de tipo hule, contra el componente de máquina movido relativamente, en tanto que el anillo recolector de aire, sobre el lado volteado al componente de máquina movido relativamente, tiene por lo menos dos cantos selladores, separados por una segunda ranura y lleva en su lado volteado al anillo en O, una cara cónica que tiene un diámetro exterior, que va creciendo axialmente hacia el lado remoto de la presión, caracterizado porque la segunda ranura tiene una base de ranura redondeada, con un radio que corresponde aproximadamente, a la profundidad radial de la segunda ranura y porque la cara cónica, evitando a la vez una modificación direccional apreciable, se mete por lo menos por encima de los planos radiales, de todos los cantos selladores, como una cara continua.
