PCT No. PCT/DE84/00092 Sec. 371 Date Dec. 14, 1984 Sec. 102(e) Date Dec. 14, 1984 PCT Filed Apr. 18, 1984 PCT Pub. No. WO84/04566 PCT Pub. Date Nov. 22, 1984.An injection line connection for internal combustion engines having for each pressure connection a connecting fitting which hitherto was upset out of the material of the injection line but which is still defective and which can be pressed by a cap nut, by way of a pressure ring, against an internal taper portion of a connecting member which carries the cap nut, is also suitable for thinner injection lines, free of disadvantages, by virtue of the following features, some of which are known and which are reproduced here by way of abstract: (a) the injection line (1) is a wall thickness in the range of from 1/5 to 1/3 of its outside diameter (D); (b) each pressure ring (6) is provided with a support projection (10) which is rounded off at the end towards the connecting fitting and which is of a tapered configuration along its outside periphery, while the associated connecting fitting (3) comprises the end of the injection line (1) which is flanged over outwardly about the support projection (10) and there forms the sealing taper portion (9); (c) the outside diameter (da) of each ring (6) is about 1.8 to three times the outside diameter (D); (d) each support projection (10) is of an axial length (L) which is in the range of the wall thickness (s) of the injection line (1), and a wall thickness (w') which is at least about 1/4 of the outside diameter (D). |
