Abstract

Perfeccionamientos introducidos en un conducto de acondicionamiento de aire para la construcción de minas y túneles, cuya envolvente flexible, que consiste por ejemplo en material sintético, forma un tubo, que junto a ambos extremos lleva sendos anillos rígidos, los cuales para el acoplamiento con un conducto contiguo, cooperan con el anillo extremo del mismo, hermetizándose mutuamente los anillos extremos encajados unos dentro de otros, preferiblemente de igual diámetro, y estando rodeados por el exterior con un manguito.
