ABSTRACT:
This invention relates to a rotary valve with multiple manifold comprising a manifold core including a plurality of ports disposed around the cylindrical surface of said manifold core, each of which ports is connected to each of a plurality of the axial holes disposed within said manifold core, a planetary roller and a belt wrapped around said manifold core and said planetary roller, which combination is enclosed within a sealed enclosure with an inlet. The other ends of said plurality of the axial holes open to the outside of said enclosure provide the multiple outlets. As the angular position of said planetary roller relative to said manifold core is varied, each of said plurality of ports disposed around the cylindrical surface of said manifold core becomes open when it is located within the unwrapped angle of said belt around said manifold core and becomes closed when it is within the wrapped angle.
