<p>A flow regulating device (2) comprising a plurality of coaxial vortex chambers (16, 116, 216, 316) disposed in flow series. Each vortex chamber (16, 116, 216, 316) has an inlet (22, 122, 222, 322) disposed to promote rotational flow within the vortex chamber (16, 116, 216, 316), and an outlet (24, 124, 224, 324). A diffusion chamber (12, 112, 212) is disposed between adjacent vortex chambers (16, 116, 216, 316), and the outlet (24, 124, 224, 324) of one and the inlet (22, 122, 222, 322) of the other of the adjacent vortex chambers (16, 116, 216, 316) open into the diffusion chamber (12, 112, 212).</p> |
