There is provided a high speed rotary valve which is relatively simple in design and which can effectively regulate the flow of fluid under high temperature conditions in such a manner as to produce perturbations in the fluid stream. Such a valve may be used to regulate the flow of fluid, e.g. air, toward a work piece to produce a perturbation in the piece for example. The clearance between the rotor and stator is such that the flow of fluid is never completely cut off, i.e., the valve continues to "leak through" the closed outlet port even when the rotor and stator openings are not aligned. Fluids having temperatures in the range of 40 to at least 900.degree. F. may be processed through this valve. The valve is also useful in creating aerosols of liquids and gases and in producing blown fibers.

[ What is claimed is:] [1.] A high speed rotary valve comprising a rotor having plurality of equally spaced, equal size apertures and a shaft at a center axis; a stator arranged adjacent said rotor having a plurality of axial fluid outlet ports which alternately communicate with said apertures as said rotor turns adjacent said stator about said shaft; and wherein said rotor and stator have a clearance gap such that flow through said ports has a perturbation amplitude of less than 20 percent; andwherein said motor and plurality of apertures are adapted to create a pulsed fluid flow having a frequency of at least about 100 Hertz; anda heat removal device and a coupling device wherein said coupling device is attached to said shaft and said motor and further wherein said heat removal device is positioned between said coupling device and said rotor.
