Abstract
A sleeve valve having control of the rate of fluid flow therethrough by rotation of an outer sleeve is disclosed. Fluid flows in through a longitudinal bore in a valve body, then outward through one or more radial apertures extending outward from the longitudinal bore. An O-ring which is mounted eccentrically within a sleeve positioned around the valve body covers the radial aperture to an amount depending upon the angular position of the sleeve with respect to the valve body. The invention encompasses both flow control and metering valves. A linear or other desired relationship between angular position of the sleeve with respect to the valve body versus flow rate of fluid through the valve may be achieved.
