Abstract

An embodiment of the invention may include a sealing apparatus. The sealing apparatus may include a first component having a body, where the body has an outer surface and a first arm protruding from the outer surface. The first arm includes an inner surface facing the outer surface of the body. The sealing apparatus may include a second component engaged by the first arm of the first component. The second component may have a first portion arranged inside a space between the inner surface of the first arm and the outer surface of the body and a second portion arranged outside of the space and adjacent to an outer surface of the first arm.

First claim

What is claimed is:

1. A sealing apparatus comprising:
a first component comprising a body, a first arm, and a second arm protruding from an outer surface of the body, the first arm comprising a first inner surface facing the outer surface of the body, wherein the first inner surface and the outer surface of the body form a first acute angle, and wherein the first inner surface and the outer surface are adjoining surfaces, and the second arm comprising a second inner surface facing the outer surface of the body and the first inner surface, wherein the second inner surface and the outer surface of the body form a second acute angle, and wherein the second inner surface and the outer surface are adjoining surfaces, and wherein the first arm includes a first portion extending from the outer surface of the body and a second portion connected outwardly to the first portion and being inclined with respect to the first portion; and
a second component attached to the first component, the second component having a first portion arranged inside a space defined between the first inner surface, the second inner surface, and the outer surface of the body and a second portion arranged outside of the space and adjacent to an outer surface of the first arm and an outer surface of the second arm, wherein the second component is a portion of a wall of a casing and is substantially perpendicular to the body of the first component.

2. The sealing apparatus of claim 1 , further comprising one or more of:
the first portion of the second component is prestressed against the first inner surface, the second inner surface, and the outer surface of the body; and
the second portion of the second component is prestressed against the outer surface of the first arm and the second arm.

3. The sealing apparatus of claim 1 , wherein a coefficient of thermal expansion of the first component is different from a coefficient of thermal expansion of the second component.

4. The sealing apparatus of claim 3 , wherein during a hot condition the coefficient of thermal expansion of difference causes a force from the first portion of the second component onto the first inner surface of the first arm.

5. The sealing apparatus of claim 3 , wherein during a hot condition the coefficient of thermal expansion of difference causes a force from the second portion of the second component onto a first outer surface of the first arm.

6. The sealing apparatus of claim 1 , wherein the outer surface of the body and the inner surface of the first arm has an oblique orientation.

7. The sealing apparatus of claim 1 , wherein the first portion extends obliquely from the outer surface of the body, and wherein the first inner surface is located on the first portion of the first arm and the second portion of the first arm facing the body.

8. The sealing apparatus of claim 1 , the second arm having a shape corresponding to a mirror image of the first arm, a corresponding mirror axis being orientated perpendicularly to the outer surface.

9. The sealing apparatus of claim 1 , wherein the first arm has the shape of a collar or a collar section extending at least partially in a circumferential direction of the outer surface of the body.

10. The sealing apparatus of claim 1 , further comprising multiple arms located circumferentially about the body of the first component, and wherein the multiple arms contain openings between each arm.

11. The sealing apparatus of claim 10 , wherein the multiple arms are staggered.

12. The sealing apparatus of claim 1 , wherein the first portion extends obliquely from the outer surface of the body and wherein the first inner surface is located on the first portion of the first arm facing the body.

13. The sealing apparatus of claim 1 , wherein the first acute angle and the second acute angle are substantially similar.

14. The sealing apparatus of claim 13 , wherein the first acute angle is between about 30° and about 80°.

15. The sealing apparatus of claim 13 , wherein the first acute angle is about 45°.
