Abstract
The present invention relates to a compressor wherein, when oil is supplied to a single module, the module can mechanically/structurally supply the oil to a plurality of regions in a selective manner according to the pressure of a refrigerant, etc.
Claims16
A compressor comprising:
- a casing;
- a driver coupled to an inner circumferential surface of the casing;
- a rotating shaft coupled to the driver and configured to enable oil to flow therethrough;
- and
- a compressing portion coupled to the rotating shaft and configured to compress refrigerant and be lubricated with the oil,
- wherein the compressing portion includes:
- an orbiting scroll including (i) an orbiting end plate supporting the rotating shaft and configured to orbit and (ii) an orbiting wrap extending along a circumference of the orbiting end plate and configured to compress the refrigerant,
- a fixed scroll including:
- a fixed end plate defining (i) a suction hole configured to receive the refrigerant and (ii) a discharge hole spaced apart from the suction hole and configured to discharge the refrigerant, and
- a fixed wrap extending from the fixed end plate and facing the orbiting wrap, the fixed wrap being configured to compress the refrigerant,
- a main frame mounted at the fixed end plate and configured to accommodate the orbiting scroll, wherein the rotating shaft extends through the main frame,
- an oil supply passage configured to supply the oil delivered from the rotating shaft through the orbiting end plate or the fixed end plate to (i) a first passage defined between the orbiting wrap and the fixed wrap and (ii) a second passage defined closer to the suction hole than the first passage is, and
- an adjusting portion being in fluid communication with the oil supply passage, the first passage, and the second passage, the adjusting portion being configured to selectively supply the oil to at least one of the first passage or the second passage,
- wherein the adjusting portion includes:
- a shielding portion configured to, based on an internal pressure of the casing, selectively open and close at least one of the first passage or the second passage, and
- a housing provided in the fixed end plate and configured to accommodate the shielding portion and enable the shielding portion to reciprocate, the housing being in fluid communication with the first passage, the second passage, and the oil supply passage, and
- wherein an end of the housing is exposed to an outside of the fixed end plate to thereby expose the shielding portion to the outside of the fixed end plate.
