Abstract

A valve with an opening surrounded by a seat, and a closure member, which, in a closed position, presses onto the seat and closes the opening and, in an intermediate position, is raised from the seat and overlaps with the opening and, in a maximum opening position, at least partially releases the opening. The valve has a first valve drive for moving the closure member between the maximum opening position and the intermediate position along a first movement track, and a second valve drive for moving the closure member between the intermediate position and the closed position along a second movement track which is at an angle to the first movement track. The valve has at least one transmission part which is provided for reversible deformation by the second valve drive, and the first valve drive acts on the closure member with the interposition of the transmission part.
