Sealing device with displaceable abutment
A flat shaped sealing device for sealing a gap between two parts having a sealing length and a sealing width from one side edge to the opposite side edge of at most 0.2-times the sealing length and having a sealing thickness from a bottom side to a top side of at most 0.2-times the sealing width. The sealing device includes a head section and an adjacent main section. The head section includes an abutment and a spring, wherein the abutment is displaceable towards the main section and the spring is therefore arranged between the abutment and the main section and is able to exert a force on the abutment.
1. A sealing device, for sealing a gap between two parts, comprising:
a flat shape and extending along a longitudinal direction over a sealing length from a foot end to a head end and having a sealing width from one side edge to an opposite side edge of at most 0.2-times the sealing length and having a sealing thickness from a bottom side to a top side of at most 0.2-times the sealing width; and comprising a head section arranged at the head end and an adjacent main section spaced apart from the head end,
wherein the head section comprises an abutment and a spring, wherein the abutment is displaceable towards the main section, and wherein the spring is arranged between the abutment and the main section and is adapted to exert a force on the abutment.
2. The sealing device according to claim 1 ,
wherein the length of the head section is at most 2-times the sealing width and at most 0.2-times the sealing length.
3. The sealing device according to claim 1 ,
wherein the main section and/or the sealing device is linear along the longitudinal direction.
4. The sealing device according to claim 1 ,
wherein a riffle structure is arranged at the bottom side of the main section.
5. The sealing device according to claim 1 ,
wherein the spring has a meandering shape.
6. The sealing device according to claim 1 ,
wherein the spring is firmly connected with the abutment and is supported by the main section; or
wherein the spring mounted between the abutment and the main section.
7. The sealing device according to claim 1 ,
wherein the spring is firmly connected with the abutment and with the main section.
8. The sealing device according to claim 7 ,
wherein the spring is designed as a bending beam and is connected to the main section via a side edge, wherein a free end of the spring forms the abutment.
9. The sealing device according to claim 8 ,
wherein two springs are arranged opposite to each other each connected with the main section via a side edge, wherein the free end of each spring forms an abutment.
10. The sealing device according to claim 1 ,
wherein the head section comprises a cover, which is arranged at the top side and is firmly connected with the main section and covers the spring.
11. The sealing device according to claim 10 ,
wherein a cover thickness of the cover is at most 0.3-times the sealing thickness; and/or
wherein the abutment protrudes beyond the cover at the head end.
12. The sealing device according to claim 10 ,
wherein the cover has a riffle structure according to a riffle structure of the main section; or
wherein the cover is flat on the top side.
13. The sealing device according to claim 10 ,
wherein the cover extends at both side edges down to the bottom side.
14. The sealing device according to claim 13 ,
wherein the cover provides a guide for the abutment, which has at least one locally increased cross section fitting into the guide enabling a sealing between the cover and the abutment.
15. The sealing device according to claim 10 ,
wherein the abutment has adjacent to the head end the sealing width and the sealing thickness.
16. The sealing device according to claim 12 ,
wherein the depth of the riffle structure is reduced.
