Abstract
A scroll type compressor includes an orbiting scroll including an orbiting wrap and a fixed scroll including a fixed wrap, in which first and second oil channels are respectively configured to supply oil to inner and outer oil channels formed by the orbiting wrap and the fixed wrap. Thus, the scroll type compressor has an oil channel structure that allows oil feeding into to the scrolls.
Claims10
A compressor comprising:
- a casing comprising a discharger configured to discharge refrigerant to an outside of the casing, the casing defining an oil storage space configured to store oil therein;
- a driver coupled to an inner circumferential surface of the casing;
- a rotatable shaft coupled to the driver and configured to transport the oil;
- and
- a compressing assembly coupled to the rotatable shaft and configured to compress the refrigerant, the compressing assembly being configured to be lubricated with the oil,
- wherein the compressing assembly comprises:
- an orbiting scroll comprising:
- an orbiting end plate that supports the rotatable shaft rotatably and is configured to perform an orbiting motion about the rotatable shaft, and
- an orbiting wrap that extends along a circumferential direction of the orbiting end plate,
- a fixed scroll comprising:
- a fixed end plate that defines a refrigerant inlet and a discharge hole spaced from the refrigerant inlet, and
- a fixed wrap that extends from the fixed end plate and faces the orbiting wrap, wherein the orbiting wrap and the fixed wrap are configured to compress the refrigerant, and the discharge hole is configured to discharge the compressed refrigerant,
- a main frame that is disposed at the fixed end plate and accommodates the orbiting scroll, wherein the rotatable shaft passes through the main frame, and
- an oil feeding channel that passes through the orbiting end plate and the fixed end plate and that is configured to supply the oil transported by the rotatable shaft into one or more regions between the orbiting wrap and the fixed wrap, the oil feeding channel comprising:
- a first oil channel configured to supply the oil to a first region between the fixed wrap and the orbiting wrap, the first oil channel having a first outlet spaced apart from the rotatable shaft, and
- a second oil channel that is separate from the first oil channel and configured to supply the oil to a second region different from the first region, the second oil channel having a second outlet spaced apart from the rotatable shaft and defined radially outward relative to the first outlet with respect to the rotatable shaft,
- wherein the first oil channel and the second oil channel are spaced apart from each other by a spacing larger than a thickness of the orbiting wrap, and
- wherein at least a portion of the first outlet and the second outlet is configured to be blocked based on rotation of the orbiting wrap relative to the fixed wrap.
