Abstract

A sealing element for a high-pressure connection, including a first portion and a second portion. The first portion is configured to dispose the sealing element in a clearance. A first side of the first portion is disposed so as to be substantially orthogonal to a second side of the second portion. The second portion has a third side, and the second portion is configured to press the third side onto a gap to be sealed when an increased ambient pressure acts on the second side.

Claims (27)

1 . A sealing element for sealing a high-pressure connection between a first component and a second component, comprising:

a first portion configured to be disposed in a clearance of the second component; and

a second portion comprising a tip,

wherein a first side of the first portion is oriented substantially horizontally relative to the second component, and a second side of the second portion is oriented substantially vertically relative to the second component,

wherein the second portion has a third side configured to be compressed so as to seal a gap when an increased ambient pressure acts on the second component, and

wherein the first side and the second side have an intersection point, and wherein the third side at least in part has a contour having a curvature about the intersection point from the tip of the second portion to a point disposed within the clearance, so as to be acted on by a bottom surface of the second component upon the increased ambient pressure.

2 . The sealing element according to claim 1 , wherein the second side and the third side are connected to one another by a rounded portion.

3 . The sealing element according to claim 1 , wherein a first length of the first side and a second length of the second side have a length ratio between 0.7 and 1.3.

4 . The sealing element according to claim 1 , wherein the first portion has a fourth side, wherein a first thickness between the first side and the fourth side, and a second thickness between the second side and the third side, have a thickness ratio between 0.5 to 1.2.

5 . The sealing element according to claim 1 , wherein the first portion has two mouldings which are configured to secure the sealing element in the clearance.

6 . The sealing element according to claim 1 , wherein the sealing element has a substantially continuous contour forming a ring.

7 . A sealing unit comprising:

a first component;

a second component; and

the sealing element according to claim 1 ,

wherein the sealing element is configured to substantially stop a fluid flow through a gap between the first component and the second component.

8 . The sealing unit according to claim 7 , wherein a height ratio between a height of the gap and a height of a clearance is up to 0.3.

9 . A system for electrolysis, comprising:

the sealing element according to claim 1 .

10 . A system for electrolysis comprising the sealing unit according to claim 7 .

11 . A sealing element for sealing a high-pressure connection between a first component and a second component, comprising:

a first portion configured to be disposed in a clearance of the second component; and

a second portion comprising a tip,

wherein a first side of the first portion is oriented substantially horizontally relative to the second component, and a second side of the second portion is oriented substantially vertically relative to the second component,

wherein the second portion has a third side configured to be compressed so as to seal a gap when an increased ambient pressure acts on the second component, wherein the second side and the third side are connected to one another by a rounded portion, and

wherein the first side and the second side have an intersection point, wherein the third side at least in part has a contour having a curvature about the intersection point from the tip of the second portion to a point disposed within the clearance, so as to be acted on by a bottom surface of the second component upon the increased ambient pressure, wherein the curvature extends from the rounded portion.

12 . The sealing element according to claim 1 , wherein the curvature merges tangentially into a straight portion parallel to the second side.
