- Fig. 4 enlarges detail A of Fig. 3;
- FIG. 5 shows a detail according to section V-V in FIG. 2;
- FIG. 6 shows a section according to VI -VI in Fig. 5.
- FIG. 7 shows an axonometric exploded view of the filling nozzle of FIG. 1 in a second embodiment
- FIG. 8 shows a vertical section according to VIII in FIG. 7
- FIG. and FIG. 9 shows a vertical section according to XI in FIG. 7.
- the fuel tank of a truck is summarily denoted by 1.
- Its wall 2 has a curvature area 3 with the axis of curvature 3 ', in which only one indicated opening 4 an inventive filler neck 5 is attached.
- an inventive filler neck 5 is attached.
- the wall 2 consists of sheet metal, in particular of a light metal sheet, and the parts of the filler neck are preferably injection-molded from a suitable plastic.
- the filler neck 5 consists of a first collar ring 8, a second collar ring 9 and a screw ring 10.
- the first collar ring 8 is in its basic form a tube 11 with a surrounding him first collar 13.
- the tube 11 ends tank outside in an outer edge 12 with means for attaching a lid (not shown here), here bayonet ramps 12 ', and extends with a tube part 11' inside the tank.
- the tube 11 is surrounded by a first collar 13 which bears against the outside of the wall 2. If the filler neck is arranged in the curved region 3 of the wall 2, as in the illustrated embodiment, the collar 13 is adapted to the curvature.
- the second collar ring 9 consists of a second collar 17 resting against the inside of the wall and a tube extension 16 extending from the latter into the interior of the container, which ends in a first contact surface 18.
- the first contact surface 18 lies in an axis-normal plane.
- the collar 17 is also adapted to the curvature of the wall 2.
- the inner diameter of the second collar ring 9 is equal to the outer diameter of the tube part 11 'of the first collar ring 8, whereby the two parts 8, 9 are centered to each other.
- On the inside of the second collar ring 9 may be a longitudinal rib 19, which produces the assignment of the two collars 13, 17 in the circumferential direction with a not visible here groove.
- the screw ring 10 is in its basic form a tube 20. At its tankinneren edge a collar 21 is provided, the second contact surface 22 cooperates with the first contact surface 18 of the second collar ring 9. On the circumference of the tube is over the collar 21, here near the upper edge, an external thread 24, which cooperates with the internal thread 14 of the first collar ring 8. At the upper edge of the screw ring 10, bores 26 for fastening additional devices, not shown, and means 27 for rotating or holding the inner part 10 can also be present.
- the filler neck can be seen in the assembled state.
- the edge zone of the opening 4 is clamped between the first contact surface 15 of the first collar 13 and the second contact surface 23 of the second collar 17.
- the two contact surfaces 15, 23 of the collar 13,17 follow the curved shape of the container wall 3. Therefore, the opening 4 in the container wall is a round hole without any formations and without flanging.
- a seal 30, 31 is attached in each of the contact surfaces 15, 23, a seal 30, 31 is attached.
- the clamping force is applied by turning the screw ring 10 with respect to the first collar ring 8 by means of the thread 14, 24.
- the screw ring 10 is executed double-walled in the illustrated embodiment, the wall parts are denoted by 20 'and 20 ".
- the opening 4 in the wall 2 has a recess 35 into which a nose 36 of the first collar ring 8 fits.
- the nose could also be 9 in the second collar ring.
- the nozzle is positioned with respect to the wall 2 angularly.
- the filler neck 5 consists of a first collar ring 108, a second collar ring 109 and a screw ring 110th
- the first collar ring 108 is in its basic form a tube with a first collar 113 surrounding it on the outside, which forms a first abutment surface 115, which rests against the inside of the wall 2 when the filler neck is mounted.
- the contact surface 115 corresponds to the curvature of the wall 2. For reasons of strength of the collar 113 extends here to the tank inner edge of the first collar ring 108th
- the collar 113 has opposite two flats 128, in each of which a snap hook 127 is formed. This (127) is used to hold the first collar ring 108 during assembly. It can also be used to determine the correct angle of the filler neck in the tank. From the first contact surface 115 of the collar 113, a cylindrical part extends to the tank outside and through the opening 4 of the wall 2, which part forms a screw neck 120 and a centering surface 125 (FIG. 8). At the tank outer edge of the screw 120 is a first thread 114, here an external thread. In the centering surface 125, a groove 126 extends in the longitudinal direction. On the inside of the first collar ring 108 may be extensions 129 for attaching attachments, either bores or others, as seen in FIG.
