Abstract

Junta de obturación para árboles, que se compone de un elemento de junta anular de material polímero que está oprimido de manera elástica, con su superficie de junta, contra la superficie antagonista formada por la superficie del árbol, estando provista la superficie de junta de, al menos, un elemento de devolución que actúa hidrodinámicamente para líquido de fuga, caracterizada porque, además de la superficie de junta, la superficie antagonista está provista de, al menos, un elemento de devolución que actúa hidrodinámicamente, y porque los elementos de devolución tienen, en la superficie de junta y en la superficie antagonista, efectos de transporte que difieren entre si.
