Abstract
Abstract A rolling rotor motor/compressor is made with a stator and both an inner and an outer rotor which serve to mechanically balance the device. The device can be configured to be a single compressor, two compressors, staged compressors as well as functioning as a motor. In the preferred embodiment the rotors are restricted to an orbiting movement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
159 words
A rolling rotor motor means comprising: housing means; stator means within said housing means and having a geometric axis, a plurality of windings and cylindrical opening therein; cylindrical rotor means having a geometric axis and located within said cylindrical opening and defining therewith a first chamber; annual rotor means having a geometric axis and located in said housing means and surrounding said stator; said annular rotor means and said housing means together defining a second chamber; whereby upon actuation of a portion of said plurality of windings, said cylindrical and annular rotor means are drawn into contact with said stator means at the location of said actuated portion of said plurality of windings such that said geometric axes of said stator means and said cylindrical and annular rotor means define a plane with said axis of said stator being between the axes of said cylindrical and annular rotor means so that said rolling rotor motor means is mechanically balanced.
Claim 2
Dependent Claim
159 words
A rolling rotor motor means comprising: housing means; stator means within said housing means and having a geometric axis, a plurality of windings and cylindrical opening therein; cylindrical rotor means having a geometric axis and located within said cylindrical opening and defining therewith a first chamber; annual rotor means having a geometric axis and located in said housing means and surrounding said stator; said annular rotor means and said housing means together defining a second chamber; whereby upon actuation of a portion of said plurality of windings, said cylindrical and annular rotor means are drawn into contact with said stator means at the location of said actuated portion of said plurality of windings such that said geometric axes of said stator means and said cylindrical and annular rotor means define a plane with said axis of said stator being between the axes of said cylindrical and annular rotor means so that said rolling rotor motor means is mechanically balanced.
Claim 3
Dependent Claim
25 words
The rolling rotor motor means of claim 1 further including means for limiting said cylindrical and annular rotor means to move orbital and radial motion.
Claim 4
Dependent Claim
49 words
The rolling rotor motor means of claim 1 further including vane means extending into said first chamber and a fluid inlet port and a fluid outlet port on either side of said vane whereby said cylindrical rotor means and said stator means coact to define a rolling rotor compressor.
Claim 5
Dependent Claim
33 words
The rolling rotor motor means of claim 3 further including vane means extending into said second chamber whereby said annular rotor means and said housing means coact to define a rolling rotor compressor.
Claim 6
Dependent Claim
48 words
The rolling rotor motor means of claim 4 wherein said rolling rotor compressor defined by said annular rotor means and said housing means defines a first stage compressor and said rolling rotor compressor defined by said cylindrical rotor means and said stator means defines a second stage compressor.
Claim 7
Dependent Claim
24 words
The rolling rotor motor means of claim 4 further including means for limiting said cylindrical and annular rotor means to orbital and radial motion.
Claim 8
Dependent Claim
33 words
The rolling rotor motor means of claim 1 further including vane means extending into said second chamber whereby said cylindrical rotor means and said stator means coact to define a rolling rotor compressor.
