Abstract

Cette invention concerne une conduite haute pression munie d'une gaine pour l'alimentation d'appareils utilisateurs hydrauliques. Cette conduite comprend un tuyau haute pression qui est placé à l'intérieur d'un tuyau formant gaine en ménageant avec celui-ci un intervalle dans lequel une certaine pression peut régner. Un dispositif de surveillance permet de surveiller la condition de pression régnant à l'interieur de cet intervalle Une conduite de ce type est utilisable dans les exploitations minières, notamment pour l'alimentation- des buses haute pression d'outils ou de machines d'abattage.
