1. A method for positioning a closure element of a valve or ejector, said closure element being movable by means of a drive between a first end position and a second end position, wherein the closure element blocks a throughflow opening of the valve or ejector in the first end position against a throughflow of fluid or gas and releases the throughflow opening in the second end position for a throughflow of fluid or gas, the method comprising:
moving the closure element into one end position of the first end position or the second end position, and
performing a compensation cycle after the closure element has been moved into the one end position,
triggering the closure element during the compensation cycle to perform a first compensation movement towards the other end position and to perform a second compensation movement towards the one end position,
wherein the closure element is triggered to perform the first compensation movement along a first distance and to perform the second compensation movement along a second distance,
wherein the second distance is greater than the first distance, and
wherein the compensation cycle is cyclically repeated.
