Abstract
A rotary valve has a valve body having at least one cylindrical hole, and casings provided with sleeves/plugs having an outer diameter substantially equal to an inner diameter of the cylindrical hole. The sleeves/plugs are provided in coaxial relation with the cylindrical hole. A flow of fluid is controlled by the relative motion between the valve body and the casings. The rotary valve may be provided with a high response time even by a small drive force.
