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 frst 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.

Dependent claims

A valve comprising

an opening surrounded by a valve seat,
a closure member that is movable from a closed position, in which the closure member is pressed onto the valve seat and closes the opening, to an intermediate position in which the closure member is raised from the valve seat and is arranged overlapping the opening, and a maximum opening position, the closure member at least partially releases the opening,
at least one first valve drive that moves the closure member at least one of to or fro between the maximum opening position and the intermediate position along a first movement track, and
at least one second valve drive that moves the closure member at least one of to or fro between the intermediate position and the closed position along a second movement track, and
the first movement track and the second movement track are arranged in an angled manner with respect to each other,
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.
