Patent ID: 6901904

Claim:
An intersecting vane machine, which comprises a supporting structure, a first rotor and at least one intersecting second rotor rotatably mounted, wherein: (a) said first rotor has a plurality of first vanes positioned on a radial 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) said second rotor has a plurality of secondary vanes positioned on a radial 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; (c) one or more intake ports which each permit flow of a fluid into a primary chamber or secondary chamber and one or more exhaust ports which each permit flow of a fluid out of said primary or secondary chamber; and (d) wherein a first width of said primary track and/or said secondary track at each point of intersection is greater than a second width of said primary and/or secondary track between each point of intersection, thereby permitting sealing between vanes in said primary and/or secondary track at said second width but not at said first width.
