DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0070] FIG. 1 shows a shell 1. FIG. 1 shows a sectional view, wherein the sectional plane is defined by the longitudinal direction L and the transverse direction Q. The longitudinal direction L and the transverse direction Q are perpendicular to each other.

[0071] The shell 1 comprises a housing 10, wherein the housing 10 delimits the interior or cavity 12 of the shell 1 with respect to the surroundings. The housing 10 has a floor 20 and a cover 30. The floor 20 and the cover 30 each delimit the shell 1 in the direction of the longitudinal direction L. For stability reasons, the floor 20 is formed integrally with the cleading 40. The cover 30, on the other hand, is fixed to the cleading 40, in particular to the cover cleading 44, by a material bond. The cleading 40 bounds the shell 1 in the transverse direction Q. Facing the cover 30, the cleading 40 has a cover cleading 44. The cover cleading 44 is mechanically connected to the bottom cleading 42 via the stabilizing element 50. Both the bottom cleading 42 and the cover cleading 44 have a constant cleading wall thickness d40.

[0072] The stabilizing element 50 is formed as a stabilizing disk, wherein the stabilizing element 50 is fixed in a material bonding manner to the shell 40 via its mounting area 52, which is formed as an outer stabilizing protuberance, namely both to the cover shell 44 and to the floor shell 42. The mounting area 52 extends in the longitudinal direction L and is formed as a protuberance in the longitudinal direction L, as already explained. In addition, the mounting area 52 limits the stabilizing element 50 in the transverse direction Q. In order to achieve a particularly advantageous stabilization of the shell 1, the mounting area 52 of the stabilizing element 50 is formed tubularly about the longitudinal direction L and rotationally symmetrically about the longitudinal direction L.

[0073] The stabilizing element 50 separates the cavity 12 into a primary subcavity 14 and a secondary subcavity 16.

[0074] For receiving the ignition tube 70 of the shell 1 extending in the longitudinal direction L, the stabilizing element 50 has an ignition tube opening 54. This ignition tube opening 54 is formed by or surrounded by the central region 56, which is formed as an inner stabilizing protuberance. The central region 56 is formed as a protuberance formed in the longitudinal direction L. The central region 56 supports the ignition tube 70, wherein the ignition tube 70 is fixed to the central region 56 by material bonding.

[0075] In the transverse direction Q between the mounting area 52 and the central region 56, the planar connecting area 58, which is formed as a disk region, of the one-piece stabilizing element 50 extends.

[0076] In order to achieve centering of the ignition tube 70, the shell 1 has a centering element 80 in the floor region. The centering element 80 is fixed in a material-bonding manner to the floor 20 as well as to the bottom cleading 42. In order to improve centering of the ignition tube 70, the centering element 80 has a centering section 82, which in the example presented is a centering protuberance 82. This centering protuberance 82 is also formed as a protuberance in the longitudinal direction L. In order to achieve a particularly good and precise arrangement of the centering element 80, the latter has in its distal end regions in the transverse direction Qa lateral protuberance 86, which is likewise formed as a protuberance in the longitudinal direction L. Via this lateral protuberance 86, the centering element 80 is connected to the bottom cleading 42 in a materially bonded manner, wherein the bottom cleading 42 is formed integrally with the floor 20. To facilitate ignition of the ignition tube 70, the centering element 80 has a central opening 84 which is formed in the transverse direction Q through the centering protuberance 82.

[0077] FIG. 2 shows a detailed view of a shell 1 in the area of the stabilizing element 50. The stabilizing element 50 has two protuberances which are formed in the same direction. This equidirectional design of the protuberances of the stabilizing element 50 is advantageously (but not exclusively) present if the stabilizing element 50 has an assembly region 52 as well as a central region 56 in the form of a protuberance in longitudinal direction L.

[0078] It is expedient that the mounting area 52 has a greater extension in the longitudinal direction L than the central region 56, as exemplified in FIG. 2.

[0079] In order to achieve a mechanical connection between the central region 56 and the mounting area 52, the stabilizing element 50 has a connecting area 58, which in the example shown is formed as a disk region. The stabilizing element 50 has a constant wall thickness d50.

[0080] In order to achieve gas passage through the stabilizing element 50, the latter has gas passage openings 59 which extend in the longitudinal direction L. Gas exchange can therefore take place through the gas passage openings 59 between two charge subspaces of the cavity 12, in particular between the primary 14 and the secondary subcavity 16.

[0081] In addition, the stabilizing element 50 also serves to provide a mechanical connection between the floor cleading 42 and the cover cleading 44, wherein both of these elements have a constant cleading wall thickness d40.

[0082] FIG. 3 shows a detailed view of the floor area of a shell 1. A centering element 80 is arranged in the floor region of the shell 1, which is characterized in the transverse direction Q by a lateral protuberance 86. In its central region, the centering element 80 has a centering section 82, wherein the central opening 84 is provided within the centering section 82.

[0083] On the outer circumference of the centering section 82 is the distal end in the longitudinal direction L of the ignition tube 70. In order to achieve a particularly mechanically resilient design, the centering element 80 is fixed to the floor 20 by a material bond. In order to facilitate ignition of the ignition tube 70, the floor 20 has an opening through which access to the central opening 84 or the interior of the centering protuberance 82 is possible from the surroundings.

[0084] FIG. 4 shows an embodiment of a shell 1 in which the ignition tube 70 is of continuous design. The ignition tube 70 is therefore connected at both distal ends, in particular in the longitudinal direction L, in each case to a centering element 80, in particular in each case to the centering section 82 of the centering element 80. The centering sections 82 extend in each case into the ignition tube 70, so that the ignition tube 70 and the centering element 80 overlap. A stabilizing element 50 is arranged between the centering elements 80, wherein the ignition tube 70 is guided through the ignition tube opening 54 of the stabilizing element 50. In order to achieve a high stability, the stabilizing element 50 is connected by a materially bond to the cleading 40 via the mounting area 52, which is formed as an outer stabilizing protuberance.
