Abstract
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.degree. 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.
Claims2
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 rotation therewith and connected to said duct for receiving fluid therefrom;
- barrier vane means in said control chamber attached to said shaft and extending radially from said shaft and forming a moveable seal with the interior wall of the duct;
- helical vane means in said control chamber attached to said shaft for rotation therewith, said helical vane means forming a helical chamber within said control chamber, its exterior edge forming a moveable seal with the interior wall of said fluid duct;
- and
- actuator means attached to said shaft for rotating said shaft about the axis of the fluid duct.
