Abstract

A vortex valve that comprises a valve body; an inlet chamber; a fluid distribution chamber; a vortex chamber; two tangential ducts through which two opposing flows are injected from the fluid distribution chamber into the vortex chamber; a displaceable control element installed at the inlet side of the tangential ducts comprising two throttling elements, such that each throttling element is actuable to reduce the flow rate through a different tangential duct; and means for imparting axial displacement to the control element differentially to actuate the throttling elements whereby to control the flow rate through the tangential ducts.
