diaphragm damper

or adjustable diaphragm aperture or similar. It is the same mechanism that cameras (diaphragm) and eyes (iris) use to adjust the aperture. The adjustment is done by having a circular opening growing/shrinking in concentric circles.

It seems to be used in the UK, not just directly translated from Swedish.
