Abstract:
A control valve for use in combination with a conduit having fluid flow therethrough for controlling the fluid flow therethrough comprising:a housing for communicating with said conduit, said housing having a first path and a second path therethrough; each of said paths having an input end substantially elliptical in shape, and an output end, each of said paths having an interior wall surface, said interior wall surface defining the interior dimension of said paths;an axle mounted in said housing, between said first and second paths, said axle selectively rotatable and having a first elongated slot therein;a elongated access slot positioned in said housing in a position in line with said axle, said elongated access slow allowing access to said first elongated slot in said axle;a diverter blade, said diverter blade substantially elliptical in shape, said diverter blade removably mountable in said first elongated slot in said axle through said access slot;said input end of said first path and said input end of said second path having an inward taper toward the output ends of said paths;said diverter blade selectively positionable between a point of contact with said interior wall surface at each of said input ends of said first path and said second path, by selective rotation of said axle; and,a seal formed by the contact of said diverter blade and said point of contact with said interior wall surface when said diverter blade is selectively positioned at either said input end of said first path, or, said input end of said second path, thereby allowing said fluid flow into one of said paths, while diverting said fluid flow at the input end of the path in which said diverter blade is positioned to form said seal.
