- 2. The fastening element of claim 1, in which the fastening element (1) has a closed ringlike form.
- 3. The fastening element of claim 1, in which the fastening element (4) has an open ringlike form.
- 4. The fastening element of claim 3, wherein the radial length of the fastening element (1) is created such that only with external exertion of force, it can be placed entirely on at least one component (11, 24) accommodated in the opening (10).
- 5. The fastening element of claim 4, wherein, on the fastening element (4), at least two engagement faces (42) are provided for the engagement by a gripping tool (43), by means of which by an expenditure of force the two ends (6) of the fastening element (4) can be urged toward each other, as a result of which the fastening element (4) is deformable such that it can be introduced into the opening (10) so as to rest entirely on the at least one component (11, 24).
- 6. The fastening element of claim 1, wherein the at least one component includes a flow rectifier (11) and a grid (13) on a carrier ring (14).
- 7. A fastening element for fastening at least one component accommodated entirely in and resting on an opening, the fastening element axially cushioning and axially securing the component in the opening, the fastening element (1, 4) comprising a closed ringlike form and for the sake of the axial cushioning is embodied in undulating form in the direction of one of the normals (2) to the area defined by the ringlike form, and for the sake of the axial securing is dimensioned to engage one of the at least one components (11, 13) accommodated inside the opening (10) and a stop edge (20) located in the opening and wherein the radial length of the fastening element (1) is such that, without external exertion of force, it can be placed entirely on said at least one component (11, 24) accommodated in the opening (10).
- 8. The fastening element of claim 7, wherein the ratio between the length of an outer edge (9) of the fastening element (4) to the circumference of the opening (10) having the smaller diameter at the level of the stop edge (20) is approximately 1:2 or greater.
- 9. A fastening element for fastening at least one component accommodated entirely in and resting on an opening, the fastening element axially cushioning and axially securing the component in the opening, the fastening element (1, 4) comprising an open ringlike form and for the sake of the axial cushioning is embodied in undulating form in the direction of one of the normals (2) to the area defined by the ringlike form, and for the sake of the axial securing is dimensioned to engage one of the at least one components (11, 13) accommodated inside the opening (10) and a stop edge (20) located in the opening and wherein the radial length of the fastening element (1) is such that, without external exertion of force, it can be placed entirely on said at least one component (11, 24) accommodated in the opening (10).
- 10. The fastening element of claim 9, wherein the ratio between the length of an outer edge (9) of the fastening element (4) to the circumference of the opening (10) having the smaller diameter at the level of the stop edge (20) is approximately 1:2 or greater.
- 11. A fastening element for axially fastening and axially cushioning at least one component entirely within and resting upon an opening having an axial stop and a recessed radial groove, said fastening element comprising, a ringlike form defining an area substantially equal to the area of the opening, said ringlike form being undulating in form in a direction normal to its said defined area, said ringlike for being dimensioned to engage one of the at least one components in the opening and to project radially into the groove in the opening when the undulations are partially axially compressed to thereby permanently secure and axially cushion the component.
- 12. A method for axially securing and axially cushioning of at least one component, accommodated and resting entirely in an opening, by means of a fastening element, in particular a fastening element including a ringlike form and for the sake of the axial cushioning is embodied in undulating form in the direction of one of the normals (2) to the area defined by the ringlike form, and for the sake of the axial securing is dimensioned to engage one of the at least one components (11, 13) accommodated inside the opening (10) and a stop edge (20) located in the opening the method comprising the steps of the at least one component (11, 13, 24) is introduced into the opening (10); then the fastening element (1) is placed against the component (11, 24); then a tool (25) is positioned against the fastening element (1); after that, the tool (25) is displaced in the direction toward the component (11, 24) until such time as the radial length of the fastening element (1) is increased by deformation such that the fastening element (1) permanently engages a stop edge (20), present in the opening (10), and the component (11, 24); and finally, the tool (25) is removed from the opening (10).
- 13. A method for axially securing and axially cushioning of at least one component, accommodated and resting entirely in an opening, by means of a fastening element, in particular a fastening element including a ringlike form and for the sake of the axial cushioning is embodied in undulating form in the direction of one of the normals (2) to the area defined by the ringlike form, and for the sake of the axial securing is dimensioned to engage one of the at least one components (11, 13) accommodated inside the opening (10) and a stop edge (20) located in the opening the method comprising the steps of first, introducing the at least one component (11, 13, 24) into the opening (10); then deforming the fastening element (4) by exertion of force by means of a gripping tool (43) and introducing the deformed fastening element into the opening (10) at the level of a stop edge (20) in the opening and of the component (11, 24); then reducing the exertion of force of the gripping tool (43) on the fastening element (4) and removing the gripping tool (43) from the opening (10), so that the fastening element (4) presses against the wall (16) of the opening (10); then by means of a pressing tool, pressing the fastening element (4) n the direction of the component (11, 24) far enough that it snaps into place between the component (11, 24) and the stop edge (20), as a result of which the radial length of the fastening element (4) increases again; and finally removing the pressing tool, as a result of which the fastening element (4) permanently engages the stop edge (20) and the component (11, 24).
