초록

An oil separator for a compressor is shown, wherein an oil separating efficiency is maximized and a material cost, a weight, and an assembly time are minimized.

대표청구항 ▼

What is claimed is: 1. An oil separator for a compressor comprising: a drive shaft including a passageway formed therein and a channel formed thereon, the passageway in communication with a suction chamber of the compressor; and a rotation imparting structure disposed on the drive shaft having a passageway formed therein, the passageway in communication with a crank chamber of the compressor and with the passageway formed in the drive shaft to provide fluid communication between the crank chamber of the compressor and the suction chamber of the compressor, wherein the channel of the drive shaft facilitates fluid communication between the passageway formed in the drive shaft and the passageway formed in the rotation imparting structure. 2. The oil separator defined in claim 1, wherein the rotation imparting structure is a rotor. 3. The oil separator defined in claim 1, wherein the passageway formed in the drive shaft includes a radially outwardly extending passageway and an axially outwardly extending passageway. 4. The oil separator defined in claim 1, further comprising a seal disposed on the drive shaft between the crank chamber and the suction chamber, wherein the seal militates against the flow of fluid directly between the crank chamber of the compressor and the suction chamber of the compressor. 5. The oil separator defined in claim 1, further comprising a hollow tube disposed on the rotation imparting structure, the hollow tube having a first end and a spaced apart second end, wherein the first end of the hollow tube is in communication with the passageway formed in the rotation imparting structure and the second end of the hollow tube is in fluid communication with the crank chamber of the compressor. 6. The oil separator defined in claim 5, wherein the hollow tube includes a bend formed therein. 7. The oil separator defined in claim 5, further comprising a porous material disposed at the second end of the tube. 8. The oil separator defined in claim 1, further comprising a porous material disposed between the passageway formed in the rotation imparting structure and the crank chamber. 9. A compressor comprising: a head including a suction chamber formed therein; a crank case including a crank chamber formed therein; a cylinder block disposed between the head and the crank case, the cylinder block having a plurality of pistons reciprocatingly disposed therein; a drive shaft rotatingly disposed in the crank chamber and having a passageway formed therein and a channel formed thereon, the passageway in fluid communication with the suction chamber; and a rotation imparting structure disposed on the drive shaft and having a passageway formed therein, the passageway in fluid communication with the crank chamber and with the passageway formed in the drive shaft to provide fluid communication between the crank chamber and the suction chamber, wherein the channel formed on the drive shaft facilitates fluid communication between the passageway formed in the drive shaft and the passageway formed in the rotation imparting structure. 10. The compressor defined in claim 9, wherein the rotation imparting structure is a rotor. 11. The compressor defined in claim 9, further comprising a hollow tube disposed on the rotation imparting structure, the hollow tube having a first end and a spaced apart second end, wherein the first end of the hollow tube is in communication with the passageway formed in the rotation imparting structure and the second end of the hollow tube is in fluid communication with the crank chamber. 12. The compressor defined in claim 11, wherein the hollow tube includes a bend formed therein. 13. The compressor defined in claim 9, further comprising a seal disposed on the drive shaft between the crank chamber and the suction chamber, wherein the seal militates against the flow of fluid directly between the crank chamber and the suction chamber. 14. The compressor defined in claim 9, further comprising a porous material disposed between the passageway formed in the rotation imparting structure and the crank chamber. 15. A method for separating a lubricant from a refrigerant in a compressor comprising the steps of: providing a drive shaft adapted to be disposed in a crank chamber of the compressor, the drive shaft having a passageway formed therein and a channel formed thereon, the passageway in fluid communication with a suction chamber of the compressor; providing a rotation imparting structure adapted to be disposed on the drive shaft and having a passageway formed therein, the passageway in fluid communication with a crank chamber of the compressor and with the passageway formed in the drive shaft to provide fluid communication between the crank chamber and the suction chamber, wherein the channel of the drive shaft facilitates fluid communication between the passageway formed in the drive shaft and the passageway formed in the rotation imparting structure; causing a mixture of a lubricant and a refrigerant to enter the passageway formed in the rotation imparting structure; and causing the drive shaft and the rotation imparting structure to rotate about an axis of rotation to cause a separation of the mixture of fluid by a centrifugal force. 16. The method according to claim 15 further comprising the steps of disposing a hollow tube on the rotation imparting structure, wherein the hollow tube has a first end and a spaced apart second end, wherein the first end is in fluid communication with the passageway formed in the rotation imparting structure and the second end is in fluid communication with the crank chamber of the compressor. 17. The method according to claim 16, further comprising the steps of disposing a seal on the drive shaft between the crank chamber and the suction chamber, wherein the seal militates against the flow of fluid directly between the crank chamber and the suction chamber.
