Abstract
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.
Claims17
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.
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.

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.
