Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
A rotary compressor provided with a center housing (22), a rotary sleeve (30) mounted in said center housing for rotation with a plurality of vanes (16) movable in a rotor (10) which is eccentrically disposed in said rotary sleeve, an air-bearing room (40) defined between the outer periphery of said rotary sleeve and the inner periphery of said center housing, a multiplicity of air-accumulating grooves (32) formed in either or both of the inner periphery of said center housing and the outer periphery of said rotary sleeve and separated from one another, a discharge chamber (41), and at least an inlet (71) formed on the inner periphery of said center housing and internally connected to either or both of said discharge chamber and a compression working space (43) confined among said rotary sleeve, air-bearing room, said rotor and said adjacent vanes to supply air to said air-bearing room, characterised in that said air-accumulating groove (32) has the suction portion thereof (32a) peripherally alined with said inlet (71).
Claim 2
Dependent Claim
167 words
A rotary compressor provided with a center housing (22), a rotary sleeve (30) mounted in said center housing for rotation with a plurality of vanes (16) movable in a rotor (10) which is eccentrically disposed in said rotary sleeve, an air-bearing room (40) defined between the outer periphery of said rotary sleeve and the inner periphery of said center housing, a multiplicity of air-accumulating grooves (32) formed in either or both of the inner periphery of said center housing and the outer periphery of said rotary sleeve and separated from one another, a discharge chamber (41), and at least an inlet (71) formed on the inner periphery of said center housing and internally connected to either or both of said discharge chamber and a compression working space (43) confined among said rotary sleeve, air-bearing room, said rotor and said adjacent vanes to supply air to said air-bearing room, characterised in that said air-accumulating groove (32) has the suction portion thereof (32a) peripherally alined with said inlet (71).
Claim 3
Dependent Claim
22 words
The rotary compressor as claimed in claim 1, wherein said inlet (71) is shaped in the form of a peripherally extending groove.
Claim 4
Dependent Claim
43 words
The rotary compressor as claimed in either of claims 1 and 2, wherein said center housing (22) is formed in the inner periphery thereof with at least a pocket (72) disposed at the upstream position of and peripherally alined with said inlet (71).
Claim 5
Dependent Claim
38 words
The rotary compressor as claimed in claim 3, wherein said center housing (22) has either or both of the compression and suction inner peripheries thereof provided with at least a pocket (72) peripherally alined with said inlet (71).
Claim 6
Dependent Claim
34 words
The rotary compressor as claimed in one of claims 1 to 4, wherein said air-accumulating groove (32) has a compression portion (32b) more sharply inclined from the peripheral direction than said suction portion (32a).
Claim 7
Dependent Claim
19 words
The rotary compressor as claimed in claim 5, wherein said compression portion (32b) is perpendicular to the peripheral direction.
Claim 8
Dependent Claim
22 words
The rotary compressor as claimed in either of claims 1 and 2, wherein said inlet (71) is inclined toward the downstream direction.
