Title: Rotating connection for a pipeline for supplying liquid fuel to air-gas torches
Inventor: TANDART JEAN-MARIE
IPC: F23D14/46
Filed: 1986-11-21
Abstract: The subject of the invention is a male/female rotating connection constituting an accessory for the pipeline for supplying liquid fuel to air-gas torches. It comprises a body 11 rotating in a socket 13 which is mounted directly on the rear fitting of the handle of the torch by means of the connecting nut 16. Its size is so small that the diameter of the body is less than or equal to the diameter of the screw thread of the nut 16. By virtue of this connection, the flexible supply hose does not roll up on itself and, since the friction opposing rotation is very low, the user is practically unaware of the rigidity of the said flexible hose. The field of application of this rotating connection is that of air-gas torches.
