Shut-off valve, composed of a container (3) provided with valve seat (4), and also a valve body (2, 22, 42) that can be moved through the opening bounded by the valve seat (4), in order to provide a seal. The valve body (2, 22, 42) is provided with a conical or spherical shut-off edge and is connected to the container (3) by way of a flexible connecting part (5). This makes it possible to move the valve body (2, 22, 42) laterally, in other words perpendicular to the direction of closing, and in this way achieve an opening of the shut-off valve. The container (3) can comprise any construction known in the prior art.

1. Valve body (2, 22, 42), comprising a plug-shaped closing part (7, 27, 47) with a closing face, and a fixing part (11, 51) which surrounds the closing part and is hingedly connected to the closing part, an extension (8, 28, 48) acting as an operating part being fitted on the closing part in the direction away from the closing face, wherein said hinged connection to the fixing part is designed in such a way that on engagement upon the operating part the closing face carries out a tilting movement, characterised in that said closing part is the closing part of a vacuum valve and said fixing part and/or said connection is/are provided with an opening (6, 46) for releasing vacuum, in which said closing face comprises a conical surface.2. Valve body according to claim 1, in which the center of said tilting movement lies substantially on the longitudinal axis of the closing part operating means.3. Valve body according to claim 1, connected by way of an elastic connection (5,25,45) to said fixing part (11).4. Valve body according to claim 1, in which said closing part is provided with a cavity (9,29,49) facing said closing face.5. Valve body according to claim 1, comprising a hardness between 35 and 45 shore.6. Shut-off valve, comprising the valve body according to claim 1, and a valve seat (4, 24, 44), in which the valve seat comprises a relatively hard material and said valve body comprises a relatively soft, deformable material.7. Shut-off valve according to claim 6, in which said connection is designed to press said valve body in the unloaded state against said valve seat.8. Valve body comprising a plug-shaped closing part (7, 27, 47) with a closing face, and a fixing part (11, 51) which surrounds the closing part and is hingedly connected to the closing part, an extension (8, 28, 48) acting as an operating art being fitted on the closing part in the direction away from the closing face, wherein said hinged connection to the fixing part is designed in such a way that on engagement upon the operating part the closing face carries out a tilting movement, characterised in that said closing part is the closing part of a vacuum valve and said fixing part and/or said connection is/are provided with an opening (6, 46) for releasing vacuum, comprising a single piece of material.9. Valve body according to claim 8, in which said closing face comprises a conical surface.10. Shut-off valve, comprising the valve body according to claim and a valve seat (4,24,44), in which the valve seat comprises a relatively hard material and said valve body comprises a relatively soft, deformable material.11. Shut-off valve according to claim 10, in which said fixing part comprises a circumferential edge with circumferential groove and said valve seat has a circumferential edge with circumferential projection (53).12. Shut-off valve according to claim 10, in which said connection is designed to press said valve body in the unloaded state against said valve seat.13. Shut-off valve according to claim 11, in which said connection is designed to press said valve body in the unloaded state against said valve seat.14. Shut-off valve, comprising the valve body according to claim 8, and a valve seat (4, 24, 44), in which the valve seat comprises a relatively hard material and said valve body comprises a relatively soft, deformable material.15. Shut-off valve according to claim 14, in which said fixing part comprises a circumferential edge with circumferential groove and said valve seat has a circumferential edge with circumferential projection (53).16. Shut-off valve according to claim 14, in which said connection is designed to press said valve body in the unloaded state against said valve seat.17. Shut-off valve according to claim 15, in which said connection is designed to press said valve body in the unloaded state against said valve seat.18. Shut-off valve with a valve body comprising a plug-shaped closing part (7, 27, 47) with a closing face, and a fixing part (11, 51) which surrounds the closing part and is hingedly connected to the closing part, an extension (8, 28, 48) acting as an operating part being fitted on the closing part in the direction away from the closing face, wherein said hinged connection to the fixing part is designed in such a way that on engagement upon the operating part the closing face carries out a tilting movement, characterised in that said closing part is the closing part of a vacuum valve and said fixing part and/or said connection is/are provided with an opening (6, 46) for releasing vacuum, in which said fixing part comprises a circumferential edge with circumferential groove and said valve seat has a circumferential edge with circumferential projection (53).19. Shut-off valve according to claim 18, in which said connection is designed to press said valve body in the unloaded state against said valve seat.
