The obturator ring (13) and the exhaust aperture (12) are preferably shaped to create a venturi effect as fluid flows past them.
An inlet pipe (7) projects into and terminates within the chamber (4) and a resilient D-section obturator ring (13) is engaged with and located about the pipe to be resiliently- movable in the chamber.
An adjuster (23) is provided for adjusting the distance by which the fluid inlet pipe (7) projects into the chamber and thus vary the distance between the obturator ring (13) and the annular exhaust aperture (12).
