Eccentrically rotatable sleeve valve

Eccentrically Rotatable Sleeve Valve, comprising a housing having at least one horizontal inlet port and outlet port and one central opening extending essentially perpendicular to said inlet port, the interface between said horizontal inlet port and the perpendicular central opening constituting a valve seat, said valve seat having a radial surface and where the center of the radius is eccentrically displaced for the center of said central housing, a flexible sleeve inserted within said central opening, a barrel-shaped core having tapered ends snugly fitting within said flexible sleeve and where the length of the cylindrical portion of said core extends beyond the cross-sectional dimension of said inlet port and where the substantial length of is sleeve exposed within said housing is supported to withstand external fluid forces by said barrel-shaped core and its tapered ends, a shaft extending through the length of said central opening and having an eccentric element, said core having a bore cooperatively engaging with the shaft and having suitably configured portions to engage said eccentric element of the shaft nd capable of causing a nutating motion of said core toward said inlet port thereby forcing the central portion of said flexible sleeve to make a complimentary motion and thereby causing the sleeve to contact the valve seat in a camming motion and to close off and prevent fluid from flowing from the inlet to the outlet port upon sufficient rotational displacement of said shaft, tapered inserts snugly engaging the inside of said flexible sleeve above and below said core, and suitable closure means attached to either terminating end of said central opening to retain and seal said flexible sleeve and a portion of said tapered inserts.
