Abstract
Official abstract text for this publication.
A valve, in particular a vacuum valve, in which, in order to close a passage opening, in particular of the valve, at least one closure member can be moved by a valve drive, starting from a maximum open position, in which the closure member opens the passage opening at least partially, first on a first partial path into an intermediate position, and the closure member can be moved, starting from the intermediate position, on at least one second partial path which is angled away from the first partial path into a closed position, in which the closure member closes the passage opening, the valve drive having at least two cylinder spaces which are loadable in each case with a pressure medium, at least one piston being mounted displaceably in each of the cylinder spaces, and the pistons being supported on one another by way of at least one prestressing element.
First claim
