Abstract (en)
[origin: WO2022122585A1] Disclosed is a vacuum valve (10) for substantially gas-tightly sealing a first valve port (31), comprising a valve seat (30), a sealing element (20) for substantially gas-tightly sealing the first valve port (31), and a drive unit (40) for imparting a movement to the sealing element (20, 120) relative to the valve seat (30, 130). The sealing element (20) is flexibly designed in such a way that in the sealing position, a three-dimensional expansion of the sealing element (20) is variable in a direction running parallel to the opening axis (A) according to the prevailing difference in pressure.
