<p>A device (10) for inducing swirling in fluid comprising a conduit (12) through which fluid is passable, and motion inducing means (14) operable to create swirling motion. In fluid passing through the device (10), the device (10) being arranged to define a single passageway (16) therethrough which enables generally unobstructed movement of fluid, and solid or semi-solid material in the fluid generally along the axis of the passageway (16). The motion inducing means (14) is shaped to blend into the internal surface (15) of the device (10) to present no projections or recesses that could obstruct flow of fluid and solid/semi-solid material in the fluid. <IMAGE></p> |
