Abstract:
A motor comprising:(a) an outer race centered about a first axis; (b) an inner race centered about a second axis; (c) wherein said first axis is different from said second axis; (d) wherein said first axis is parallel to said second axis; and (e) a first vane coupled for movement relative to a first portion of said inner race; (f) a second vane coupled for movement relative to a second portion of said inner race; said first and second vanes defining a one-piece U-shaped cutout portion; (g) wherein said inner race is rotatable between a first position wherein said outer race is closer to said first portion of said inner race than said second portion of said inner race, and a second position wherein said outer race is closer to said second portion of said inner race than said first portion of said inner race (h) wherein said first portion of said inner race is provided with a first aperture; (i) wherein said first vane extends at least partially into said first aperture; (j) wherein said first vane is adapted for movement relative to said first aperture; (k) wherein said second portion of said inner race is provided with a second aperture; (l) wherein said second vane extends at least partially into said second aperture; (m) wherein said second vane is adapted for movement relative to said second aperture; (n) wherein said inner race is also provided with an interior and an exterior; (o) first means coupled to said first vane for retracting at least a first portion of said first vane through said first aperture into said interior of said inner race as said inner race rotates toward said first position and for extending at least a second portion of said first vane through said first aperture to said exterior of said inner race as said inner race rotates toward said second position; and (p) second means coupled to said second vane for retracting at least a first portion of said second vane through said second aperture into said interior of said inner race as said inner race rotates toward said second position and for extending at least a second portion of said second vane through said second aperture to said exterior of said inner race as said inner race rotates toward said first position.
