Abstract

Conduite de refoulement de carburant pour moteur à combustion interne à pressions d'injection très elevées. Elle comprend un tube 2 dont les sections 4 de plus grand diamètre servent d'appuis à un tube enveloppe 3. Les cavités 5, entourant les sections de moindre diamètre, communiquent entre elles par des gorges 6. Le tube 2 est réalisé à partir d'une pièce massive, par enlevement de copeaux, puis l'ensemble 2, 3 est cintré pour fermer la conduite 1.Fuel delivery line for internal combustion engine with very high injection pressures. It comprises a tube 2 whose sections 4 of larger diameter serve as supports for an envelope tube 3. The cavities 5, surrounding the sections of smaller diameter, communicate with each other by grooves 6. The tube 2 is made from '' a solid part, by removing chips, then the assembly 2, 3 is bent to close the pipe 1.
