Device for adjusting fluid flow rates, including a path length which can possibly be adjusted between an inlet (1) and an outlet (2), characterised in that it comprises, in combination, at least two flat cooperating pieces (4, 5) in contact via a plane face, overall, and, hollowed out between these two pieces in the plane face of at least one of the two pieces, a channel (6), the length of which is greater than twice the periphery of each of these two pieces.
