Abstract
Abstract An oil separator which is accomodated within a compressor utilized in a comparatively small refrigerator such as an automobile air conditioner. Generally, an oil separator is arranged next to an outlet port of the compressor in order to separate lubricant intermixed in the compressed gaseous refrigerant therefrom. The oil separator is provided with a double barrelled cylindrically shaped separation chamber, the one end of which is blocked and the other end of which is connected with multi layered filter elements and further is blocked by an end plate thereon. The separation chamber is provided with a gas conduit opening in the tangential direction thereof to communicate with a passage. Furthermore a pipe is projected extending over one end of said separation chamber to a pressure chamber in the compressor. Accordingly gaseous refrigerant loaded with lubricant therein, is introduced into the separation chamber through said gas conduit and undergoes a centrifugal force and so lubricant is separated through said separating action and is passes through multilayered filter elements to thereby be repeatedly separated. The gas which oil is separated therefrom, is introduced into a pressure chamber and is exhausted from an outlet port.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
281 words
In a gas compressor having an outer compressor housing, an inner compressor housing having a compressor rotor therein, wherein said inner compressor housing is smaller than said outer compressor housing and disposed within said outer compressor housing and defines a pressure chamber within said outer compressor housing between said outer and said inner compressor housings, the improvement comprising: an oil separator within said outer compressor housing and within said pressure chamber, said oil separator comprising means defining a plurality of cylindrical separation chambers each having a respective gas inlet conduit oriented to introduced gas tangentially into its corresponding cylindrical separation chamber and each cylindrical separation chamber having an open end and a closed end, a plurality of gas-oil separation elements each disposed for closing an open end of a respective cylindrical separation chamber, each gas-oil separation element comprising a gas permeable material effective for separating oil particles carried by a gas from the gas as it passes through said gas-oil separation element, and a plurality of gas outlet pipes each extending from the interior to the exterior of a respective cylindrical separation chamber for providing communication between the interiors of the respective cylindrical separation chambers and the pressure chamber, wherein the respective ends of said gas outlet pipes remote from said cylindrical separation chambers terminate adjacent said outer compressor housing so that gas flowing out of said cylindrical separation chambers through said gas outlet pipes and carrying oil particles impacts against said outer compressor housing to effectuate gas-oil separation; and said inner compressor housing including gas outlet openings opening into the gas inlet conduits of said oil separator for separating oil particles carried by gas discharged from said inner compressor housing.
Claim 2
Dependent Claim
281 words
In a gas compressor having an outer compressor housing, an inner compressor housing having a compressor rotor therein, wherein said inner compressor housing is smaller than said outer compressor housing and disposed within said outer compressor housing and defines a pressure chamber within said outer compressor housing between said outer and said inner compressor housings, the improvement comprising: an oil separator within said outer compressor housing and within said pressure chamber, said oil separator comprising means defining a plurality of cylindrical separation chambers each having a respective gas inlet conduit oriented to introduced gas tangentially into its corresponding cylindrical separation chamber and each cylindrical separation chamber having an open end and a closed end, a plurality of gas-oil separation elements each disposed for closing an open end of a respective cylindrical separation chamber, each gas-oil separation element comprising a gas permeable material effective for separating oil particles carried by a gas from the gas as it passes through said gas-oil separation element, and a plurality of gas outlet pipes each extending from the interior to the exterior of a respective cylindrical separation chamber for providing communication between the interiors of the respective cylindrical separation chambers and the pressure chamber, wherein the respective ends of said gas outlet pipes remote from said cylindrical separation chambers terminate adjacent said outer compressor housing so that gas flowing out of said cylindrical separation chambers through said gas outlet pipes and carrying oil particles impacts against said outer compressor housing to effectuate gas-oil separation; and said inner compressor housing including gas outlet openings opening into the gas inlet conduits of said oil separator for separating oil particles carried by gas discharged from said inner compressor housing.
Claim 3
Dependent Claim
29 words
In a gas compressor according to claim 1, wherein the respective remote end portions of said gas outlet pipes generally conform to the shape of said outer compressor housing.
Claim 4
Dependent Claim
61 words
In a gas compressor according to claim 1 or 2, wherein said gas outlet pipes each have an inner diameter along their length, and an end portion within the respective cylindrical separation chamber having an inner diameter smaller than the inner diameter along the outlet pipe length for constricting gas flow through the pipe end portion having the smaller inner diameter.
