  • This device allows the diminished tip to enter the center of a hose of any hydraulic or pneumatic system, while the hose is inserted into the box, and by crimping procedure of the box, the hose and the tube are fixed; without the need of using any type of welding, reducing manufacturing time and giving greater security by not presenting possibilities of leakage due to welding defects.

Abstract

L'invention concerne un insert-tube pour tuyaux de systèmes hydrauliques ou pneumatiques, formé de deux composants. Le premier composant est un tube métallique, globalement recouvert de nylon, comprenant un épaulement situé à proximité d'une de ses extrémités et possédant, entre l'épaulement et l'extrémité du tube, un diamètre réduit obtenu selon un procédé de diminution et d'extrusion. Le second composant est un logement, usiné ou forgé, dont les dimensions dépendent de son application, comprenant dans sa paroi inférieure interne une cavité de logement et d'assemblage destinée à recevoir ledit épaulement. Une fois ces composants assemblés, on introduit un tuyau d'un système hydraulique ou pneumatique quelconque dans ledit logement de façon que l'extrémité de diamètre réduit pénètre dans le centre du tuyau, puis on procède au sertissage du logement pour que le tuyau et le tube restent assemblés. Cette invention concerne par conséquent un tube pour tuyaux, sensiblement différent de ceux existant à l'heure actuelle sur le marché, grâce à son architecture interne innovante dont la caractéristique principale est l'absence de soudures.
