Abstract:
1. An intersecting vane machine, which comprises a supporting structure having an inside surface, a first rotor and at least one intersecting second rotor rotatably mounted in said supporting structure, wherein: (a) said first rotor has a plurality of first vanes positioned on a radially inner peripheral surface of said first rotor, with spaces between said first vanes and said surface defining a plurality of primary chambers, which said first vanes and said primary chambers travel in a primary track; (b) an intake port which permits flow of a fluid into said primary chamber and an exhaust port which permits exhaust of the fluid out of said primary chamber; (c) said second rotor has a plurality of secondary vanes positioned on a radially outer peripheral surface of said second rotor, with spaces between said secondary vanes and said surface defining a plurality of secondary chambers, which said secondary vanes and said secondary chambers travel in a secondary track; (d) a first axis of rotation of said first rotor and a second axis of rotation of said second rotor arranged so that said axes of rotation do not intersect, said first rotor, second rotor, first vanes and secondary vanes being arranged so that said first vanes and said secondary vanes intersect at only one location during their rotation; and (e) wherein a first width of said primary track at a point proximal to the point of intersection is greater than a second width of said primary track between each point of intersection and the primary chamber, thereby permitting sealing between said primary vanes and said primary track at said second width but not at said first width.
