FLAT GASKET

Abstract

A flat gasket, comprising a support body, wherein the support body has at least two segments which are fixed to one another in a positive-locking manner, wherein the segments each have two main sides, wherein a sealing contour is arranged on at least one main side of each segment.

Claims

1. A flat gasket, comprising a support body having at least two segments which are fixed to one another in a positive-locking manner, wherein the segments each have two main sides, and wherein a sealing contour is arranged on at least one main side of each segment.

2. The flat gasket according to claim 1, wherein the first segments are rod-shaped.

3. The flat gasket according to claim 1, wherein the second segments are angled.

4. The flat gasket according to claim 1, wherein the segments are provided with positive-locking elements at the edges adjacent to one another.

5. The flat gasket according to claim 1, wherein the sealing contour is made of elastomeric material and is materially bonded to the segments.

6. The flat gasket according to claim 1, wherein the sealing contour is profiled.

7. The flat gasket according to claim 4, wherein the positive-locking elements have a connecting area and a sealing area.

8. The flat gasket according to claim 7, wherein the sealing contour extends into the sealing area in each case.

9. The flat gasket according to claim 8, wherein in order to form first positive-locking elements, a recess is made in a segment, wherein the edge regions bounding the recess have a sealing contour on at least one main side, and in that second positive-locking elements have a tongue which is formed from a segment and is shaped congruently with the recess, which tongue is provided with a sealing contour on at least one main side.

10. The flat gasket according to claim 7, wherein the connecting area has a dovetail connection.

Description

[0019] Some embodiments of the flat gasket according to the invention are explained in more detail below using the figures. These show, each schematically:

[0020] FIG. 1 a flat gasket;

[0021] FIG. 2 a detail view of the flat gasket in the area of the edges of two adjacent segments.

[0022] FIG. 1 shows a flat gasket 1 comprising a support body 2 made of tough material, in the present embodiment metal. The support body 2 has a plurality of segments 3′, 3″ which are positively fixed to one another. The segments 3′, 3″ each have two main sides 4, 5. A sealing contour 6 is arranged on a main side 4 of each segment 3′, 3″.

[0023] First segments 3′ are rod-shaped and second segments 3″ are angled and have two 90-degree angles in the present embodiment. The flat gasket 1 according to FIG. 1 comprises four first segments 3′ and two second segments 3″. The segments 3′, 3″ are positively fixed to each other and form a rectangular flat gasket 1.

[0024] The segments 3′, 3″ have positive-locking elements 8 at the adjacent edges 7 which are shaped congruently with one another.

[0025] The sealing contours 6 are made of elastomeric material and are materially bonded to the segments 3′, 3″. The sealing contour 6 is applied to the segments 3′, 3″ of the support body 2 by means of injection moulding. The sealing contour 6 is profiled on the side facing away from the segments 3′, 3″.

[0026] Circular apertures 14 are made in the segments 3′, 3″ at regular intervals.

[0027] FIG. 2 shows the connecting area 9 of two adjacent segments 3′, 3″ in detail. It can be seen that the positive-locking elements 8 have a connecting area 9 and a sealing area 10. In each case, the sealing contour 6 extends into the sealing area 10.

[0028] For forming first positive-locking elements 8′, a recess 11 is formed in a segment 3′, 3″, wherein the edge regions 12 bounding the recess 11 have the sealing contour 6 on at least one main side 4. Second positive-locking elements 8″ have a tongue 13 formed from a segment 3′, 3″ and shaped congruently with the recess 11, which is provided with the sealing contour 6 on a main side 4.

[0029] The connecting area 9 is spaced from the sealing area 10 and has a dovetail connection.
