Abstract

A closure device ( 1 ) for an opening ( 2 ) in a chamber wall ( 3 ) is provided, wherein the closure device ( 1 ) has at least one closure element ( 4 ) and at least one closure element carrier body ( 5 ) and at least one yoke ( 6 ). The closure element ( 4 ) is fixedly connected to the yoke ( 6 ) by the closure element carrier body ( 5 ), wherein the yoke ( 6 ) is mounted in a housing ( 9 ) of the closure device ( 1 ) in such a way that the yoke can be slid by at least one cylinder-piston drive unit ( 7 ) of the closure device ( 1 ), in particular parallel to a longitudinal extent ( 8 ) of the closure element carrier body ( 5 ). The yoke ( 6 ) has at least one cylinder cavity ( 10 ) of the cylinder-piston drive unit ( 7 ) and/or at least one guide element receptacle ( 11 ) for guiding a guide element ( 12 ) of the closure device ( 1 ).

First claim

The invention claimed is:

1. A closure device for an opening in a chamber wall, the closure device comprising:
a closure member,
a closure member carrier body,
a yoke,
a housing,
a cylinder-piston drive unit,
the closure member is rigidly connected to the yoke via the closure member carrier body, the yoke is mounted in the housing of the closure device so as to be displaceable by the cylinder-piston drive unit, the yoke has at least one cylinder cavity of the cylinder-piston drive unit and at least one guide element receptacle for guiding a guide element of the closure device.

2. The closure device as claimed in claim 1 , wherein the cylinder cavity of the yoke comprises two cylinder cavities, and the cylinder-piston drive unit comprises two cylinder-piston drive units.

3. The closure device as claimed in claim 2 , wherein the cylinder cavities are arranged axis symmetrically to one another.

4. The closure device as claimed in claim 1 , wherein the yoke is formed as a one-piece body.

5. The closure device as claimed in claim 4 , wherein the yoke comprises a cast body or an injection-molded body or a body forged or worked from a block.

6. The closure device as claimed in claim 1 , wherein the cylinder cavity is defined by a cylinder cavity wall of the yoke, and the cylinder cavity wall and a carrier body receptacle of the yoke that fixes the closure member carrier body on the yoke are arranged in a fixed spatial position with respect to one another in the yoke.

7. The closure device as claimed in claim 1 , wherein the cylinder cavity has a cavity longitudinal axis, and said cavity longitudinal axis is arranged parallel to a longitudinal extent of the closure member carrier body.

8. The closure device as claimed in claim 1 , wherein the guide element receptacle has a guide element receptacle longitudinal axis, and said guide element receptacle longitudinal axis is arranged parallel to a longitudinal extent of the closure member carrier body.

9. The closure device as claimed in claim 1 , wherein the closure member is mounted in the housing of the closure device so as to be displaceable relative to the opening exclusively linearly and exclusively in two mutually opposite directions.

10. The closure device as claimed in claim 1 , wherein the guide element is formed as a rail, a rod or a body that is elongated parallel to a longitudinal extent of the closure member carrier body.

11. The closure device as claimed in claim 1 , wherein the guide element receptacle of the yoke comprises two guide element receptacles, and the guide element comprises two guide elements that are guided by the two guide element receptacles.

12. The closure device as claimed in claim 11 , wherein the guide element receptacles are arranged axis symmetrically to one another.

13. The closure device as claimed in claim 1 , further comprising a carrier body receptacle of the yoke that fixes the closure member carrier body on the yoke, and the guide element receptacle and the carrier body receptacle are arranged in a fixed spatial position with respect to one another in the yoke.
