ABSTRACT:
A rotary valve including a housing with a cylindrical bore enclosing a rotatably mounted cylindrical tube. The cylinder has a first array of apertures and the housing has a second array of apertures. Each aperture of the first array aligns with an aperture of the second array once during a revolution of the cylinder so that pressurized fluid in the cylinder is ejected through the aligned apertures. The device has numerous applications such as in controlling the loading of transport tubes with fragile integrated circuit packages as well as in providing driving force in a conveyor system and distributing water in an irrigation system.
