Abstract
A fluid control valve which avoids wear, cavitation, and high noise level operation and yet is substantially non-clogging. The valve includes one or more nozzles through which fluid is passed, thereby producing a fluid jet, the fluid subsequently being spun tangentially within an annular whirl chamber, and then being passed through a labyrinth passageway comprising a series of inwardly spaced concentric sleevelike annuli.
