Abstract

La presente invención se refiere a un sellado para pistón o vástago que comprende un anillo raspador hecho de material PTFE, situado en una primera ranura abierta radialmente hacia la parte de máquina desplazada relativamente y un anillo en O de material elástico del tipo de hule en que el anillo en O toca al anillo raspador con entrada en una segunda ranura y apoya sobre la base de la primera ranura, en que el anillo raspador entra en contacto con la parte de máquina desplazada relativamente cuando menos con dos cantos selladores circundantes que poseen una separación axial entre ellos y en que la segunda ranura tiene en dirección hacia su desembocadura un largo creciente en sentido axial y está delimitada en la dirección del anillo raspador por área de apoyo, caracterizado porque el área de apoyo pasa axialmente por encima de los planos radiales de la totalidad de los cantos selladores presentes como un plano de extensión continuo.
