A fluid control apparatus for proportionally directing fluid from a single conduct to multiple exhaust ports around the periphery of the duct. A controller is provided which is rotatably supported in the duct by an axial shaft. The shaft supports a radial barrier vane extending along its length and a helical vane forming a single 360°helical wall surrounding the shaft. Rotation of the controller exhaust to shaft axis directs the fluid to the appropriate exhaust ports according to its angular position.


A fluid control apparatus for controlling the direction of flow of a pressurized fluid comprising: a fluid duct for containing a pressurized fluid, said duct having an axis defining a direction of flow in the duct; fluid exhaust means arranged around the periphery of said duct for exhausting fluid in a specified direction; rotary fluid control means for directing fluid flow to preselected exhaust means, said fluid control means comprising; a shaft supported in said duct for rotation about the axis of said duct; a control chamber mounted on said shaft for...
