Abstract

An electrical switching device includes a switching path and a flow device with a control valve. By way of the flow device, a fluid can flow on the switching path. The control valve additionally has a valve body. The valve body is pressed into a sealing position by the flow pressure of the flowing fluid.

First claim

The invention claimed is:

1. An electrical switching device, comprising:
a switching path;
a flow device with a control valve for applying a flow of a flowing fluid to said switching path;
said control valve having a movable valve body, a first stop, and a second stop;
said valve body being movably disposed in a clearance fit between said first and second stops, and said valve body being formed with a through-opening; and
said valve body being configured to be pressed into a sealing position by way of a flow pressure of the flowing fluid wherein said through-opening is sealed closed by one of said first or second stops in the sealing position.

2. The electrical switching device according to claim 1 , wherein said valve body is elastically deformable.

3. The electrical switching device according to claim 1 , wherein said valve body is spatially fixed.

4. The electrical switching device according to claim 3 , wherein said valve body is spatially fixed at least at one point.

5. The electrical switching device according to claim 1 , wherein one of said first and second stops is configured to spatially fix said valve body.

6. The electrical switching device according to claim 1 , wherein one of said first and second stops is formed with a convex stop face for said valve body.

7. The electrical switching device according to claim 1 , wherein said control valve is positioned in a stationary position relative to said switching path.

8. The electrical switching device according to claim 1 , wherein the electrical switching device is a grounding switch.

9. The electrical switching device according to claim 8 , configured as a fast-acting grounding switch.
