Abstract

A two-rotor, sliding vane rotary compressor for compressing fluid containing an inner rotor, an outer rotor, means for rotating said inner rotor and said outer rotor at the same angular velocity, and at least one sliding vane disposed between the inner rotor and said outer rotor. The outer rotor is has an inner surface which is has at least one flat portion. As the inner rotor rotates, the sliding vane contacts the outer rotor.

Claims

1. A two-rotor, sliding vane rotary compressor for compressing fluid comprising an inner rotor, an outer rotor, means for rotating said inner rotor and said outer rotor at the same angular velocity, and at least one sliding vane disposed between said inner rotor and said outer rotor, wherein:

(a) said outer rotor is comprised of an inner surface, and said inner surface is comprised of at least one flat portion, whereby, as said inner rotor rotates, said sliding vane contacts said outer rotor;

(b) said inner rotor is supported by support shafts on each of its ends;

(c) said compressor is comprised of a first end plate located on a first end of said inner rotor and a second end plate located on a second end of said inner rotor, wherein each of said first end plate and said second end plate supports said inner rotor through a first set of bearings;

(d) said compressor is comprised of a center housing with a circular interior that is eccentric to said inner rotor, said housing being disposed between said first end plate and said second end plate;

(e) said outer rotor has a circular exterior that surrounds said inner rotor but is eccentric thereto;

(f) said outer rotor is mounted on a second set of bearings disposed in said first end plate and said second end plate.

2. A two-rotor, sliding member rotary compressor for compressing gas comprising an inner rotor, an outer rotor, means for rotating said inner rotor and said outer rotor at the same angular velocity, and at least one sliding member disposed between said inner rotor and said outer rotor, wherein:

(a) said inner rotor is comprised of an outer surface, and said outer surface is comprised of at least one flat portion whereby, as said inner rotor rotates, said sliding member slides on said flat surface on said inner rotor and a coacts with said outer rotor;

(b) said inner rotor is supported by support shafts on each of its ends;

(c) said compressor is comprised of a first end plate located on a first end of said inner rotor and a second end plate located on a second end of said inner rotor, wherein each of said first end plate and said second end plate supports said inner rotor through a first set of bearings;

(d) said compressor is comprised of a center housing with a circular interior that is eccentric to said inner rotor, said housing being disposed between said first end plate and said second end plate;

(e) said outer rotor has a circular exterior that surrounds said inner rotor but is eccentric thereto;

(f) said outer rotor is mounted on a second set of bearings disposed in said first end plate and said second end plate.
