Abstract
Abstract A regenerative compressor in accordance with the invention described herein comprises a stator and a rotor coaxial therewith to form a motor. Concentric to the motor and between its ends is a compressor chamber having inlet and exhaust openings. A compressor wheel is mounted on the rotor and projects into the compressor chamber for providing a high compression output in a limited space.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
A regenerative compressor comprising a cEntrally disposed stator assembly, a rotor assembly surrounding said stator assembly and operatively associated therewith to form an electric motor, a housing secured to said stator, said housing partially defining an annular and substantially closed compression chamber surrounding said rotor assembly and disposed substantially between the ends thereof, said chamber being concentric with said stator assembly and said rotor assembly, a ring rigidly secured to said rotor defining at least a part of the innermost surface of said chamber, a plurality of regenerative compressor blades depending from said ring and extending into said chamber whereby gases which enter said chamber are compressed as they are forced to move through a substantial portion thereof in a circulatory manner.
Claim 2
Dependent Claim
122 words
A regenerative compressor comprising a cEntrally disposed stator assembly, a rotor assembly surrounding said stator assembly and operatively associated therewith to form an electric motor, a housing secured to said stator, said housing partially defining an annular and substantially closed compression chamber surrounding said rotor assembly and disposed substantially between the ends thereof, said chamber being concentric with said stator assembly and said rotor assembly, a ring rigidly secured to said rotor defining at least a part of the innermost surface of said chamber, a plurality of regenerative compressor blades depending from said ring and extending into said chamber whereby gases which enter said chamber are compressed as they are forced to move through a substantial portion thereof in a circulatory manner.
Claim 3
Dependent Claim
24 words
A regenerative compressor according to claim 1 wherein said ring is fixedly secured to said rotor assembly at a point intermediate the ends thereof.
Claim 4
Dependent Claim
18 words
A regenerative compressor according to claim 1 wherein said housing defines at least three sides of said chamber.
Claim 5
Dependent Claim
32 words
A regenerative compressor according to claim 1 wherein said ring defines a fractional part of the innermost surface of said chamber and the remainder of said chamber is defined by said housing.
Claim 6
Dependent Claim
15 words
A regenerative compressor according to claim 4 wherein said chamber is generally toroidal in shape.
Claim 7
Dependent Claim
30 words
A regenerative compressor according to claim 1 wherein said chamber is of substantially constant cross-sectional area and said regenerative compressor blades extend to the outermost surface that defines said chamber.
Claim 8
Dependent Claim
55 words
A regenerative compressor according to claim 1 wherein said rotor assembly includes a cup-shaped member surrounding the stator assembly, a portion of which forms a step around its periphery, and said ring includes a lip which butts against two surfaces of said step to provide a rigid joint between said ring and said rotor assembly.
