A hermetic compressor is provided, including a casing, having a suction pipe and discharge pipe connected thereto, a driving motor installed within the casing, a compressing device installed within the casing and operated by the driving motor to form compression chambers, an oil separator that separates oil from a refrigerant discharged from by compressing device, and an oil collecting pipe through which the oil separator communicates with the compression chambers. With this structure, oil can be appropriately supplied to one or more compressors based on capacity, thus improving reliability of oil distribution and enhancing compressor performance.

An oil feeding propeller of a scroll compressor for preventing deterioration of oil feeding generated when a rotation shaft is rotated in reverse is disclosed. The propeller is tightly fitted into the lower side of the oil passage of the rotation shaft, sucks oil into the shell due to rotation shaft of shaft to raise oil to a compression part of the scroll compressor. The propeller includes a plate without operative direction for feeding oil in a predetermined direction so as to raise a predetermined quantity of oil regardless of the rotation direction shaft.

An apparatus for varying the capacity in a scroll compressor, comprising: an orbiting scroll provided with a wrap filling portion which is stepped at a certain height, extending the entire inside of a wrap from an outer end portion of the wrap; a fixed scroll provided with a stepped wrap obtained by stepping a wrap corresponding to the wrap filling portion of the orbiting scroll and being in meshing arrangement with the orbiting scroll; a connection passage for connecting compression pockets formed by the outer wrap portion of the orbiting scroll and the inside of the wrap of the fixed scroll opposed to the outside of the outer wrap portion with the suction opening; and an opening/closing unit for opening or closing the connection passage such that the suction opening side and the compression pockets can be connected and disconnected to each other, so that manufacturing unit cost can not only be reduced but also greatly widen a range of varying the capacity.

To a hermetic compressor and a refrigeration cycle device having the same, an oil separator for separating oil from a refrigerant discharged from a compression unit is added. Separated oil is recollected into an oil pump driven by a driving motor. Because refrigerant separated from the oil is prevented from being re-introduced into the compressor, a cooling capability of the refrigeration cycle device may be enhanced. Because the oil pump is driven by the driving force of the driving motor, the compressor may have a simplified configuration, and the fabrication costs may be reduced. The oil used for a crankshaft lubrication process is returned to the oil pump by forming an oil pocket between bearing surfaces of a crankshaft and the oil pump, oil may be prevented from back-flowing to the oil separator from the crankshaft. This may allow oil to be smoothly recollected into the oil pump.

Disclosed are a hermetic compressor and a refrigeration cycle device having the same. An oil separator for separating oil from a refrigerant is installed outside a casing. The oil separated by the oil separator is recollected into the casing by an oil pump driven by a driving force of a driving motor. The oil is recollected from the refrigerant and fabrication costs are be reduced. A cooling capability of the refrigeration cycle device is enhanced, the compressor has a simplified configuration, and the fabrication costs are reduced. Because an outlet of a discharge opening through which oil is discharged to the casing from the oil pump is installed at a position lower than a minimum level of oil in the casing, the refrigerant is prevented from backflowing into an oil passage, and the occurrence of air bubbles on the surface of oil in the compressor may be prevented.

An oil pump for a compressor is provided. The oil pump includes a pump body, a driving shaft coupled to the pump body, with a supply passage extending therethrough, and a plurality of pumping members which rotate with the driving shaft. Fluids such as oil are inhaled into the pump through various intakes, and the inhaled oil is directed towards the driving shaft, where the oil is supplied to the friction parts of the compressor for lubrication. The plurality of intakes into the pump provide for a continuous supply of oil to the friction parts.

A scroll compressor and a refrigerating machine including the same are provided. In the scroll compressor, an oil supply hole formed in an orbiting scroll guides oil from a space between a frame and the orbiting scroll to a space between a fixed scroll and the orbiting scroll, and an oil supply groove formed at the fixed scroll maintains communication with the oil supply hole, thereby rapidly supplying oil to a bearing surface between the fixed scroll and the orbiting scroll before the oil is introduced into a back pressure chamber. This enhances compressor efficiency by effectively preventing frictional losses and refrigerant leakage in such a compressor, and enhances energy efficiency for a refrigerating machine using such a compressor.
