Abstract
A motor for converting fluid pressure to rotational motivation and pump for moving fluid, comprising a first drum provided within a second drum. The first drum is provided with a pair of vanes, each provided with a generally heart-shaped slot around a drum shaft. The orientation of the drum shaft and shape of the slots cause the vanes to extend and retract relative to the inner drum as fluid pressure or mechanical motion rotate the inner drum relative to the outer drum.
Claims23
A motor comprising:
- (a) an outer race;
- (b) an inner race provided within said outer race;
- (c) means coupled to said inner race for centering said inner race on a first axis as said inner race rotates;
- (d) a shaft provided a long a second axis, wherein said second axis is different than said first axis;
- (e) a vane coupled to said shaft;
- (f) an end provided on said vane;
- and
- (g) means coupled to said vane for moving said end arcuately relative to said shaft.

A motor comprising:
- (a) an outer race;
- (b) an inner race provided within said outer race, said inner race defining a first slot and a second slot;
- (c) means coupled to said inner race for centering said inner race on a first axis as said inner race rotates;
- (d) a shaft provided along a second axis, wherein said second axis is different than said first axis;
- (e) a first vane having a first end provided through said first slot and coupled to said shaft;
- (f) a second vane having a second end provided through said second slot and coupled to said shaft;
- (g) wherein said first vane and said second vane are angled greater than ninety degrees from one another;
- and
- (h) means coupled to said first vane and said second vane for substantially extending and retracting said first vane and said second vane in unison relative to said shaft.

A motor comprising:
- (a) an outer race;
- (b) an inner race provided within said outer race;
- (c) means coupled to said inner race for centering said inner race on a first axis as said inner race rotates;
- (d) a shaft provided a long a second axis, wherein said second axis is different than said first axis;

- (g) a first block coupled to said first vane, said first block defining a first arcuate slot through which is provided said shaft;
- (h) a second block coupled to said second vane, said second block defining a second arcuate slot through which is provided said shaft;
- (i) said inner race and said outer race defining interstice of a substantially constant separation along at least one hundred and fifty degrees of an interior surface of said outer race;
- and
- (j) said inner race and said outer race defining a space therebetween greater than interstice collectively along at least forty degrees of said interior surface of said outer race.
