Abstract (en)
[origin: WO2022175327A1] The invention relates to a valve (10) for opening and closing a valve opening (11) in a gas-tight manner and for ventilating a vacuum volume, having a valve seat (30), a closure element (20), and an adjusting unit (40) which is designed to provide a movement of the closure element (20) relative to the valve seat (30) such that the closure element (20) can be adjusted from an open position into a closing position and back. The valve seat (30), the closure element (20), and the adjusting unit (40) are arranged such that the closure element (20) can be adjusted linearly along an opening axis (A). The valve (10) has a holding device (50) which is designed to hold the closure element (20) in the closing position by providing a holding force.
