Abstract:
A scroll compressor is provided that may include a differential pressure hole formed at or in an orbiting scroll that communicates a high pressure part with an intermediate pressure part, a decompression portion formed in the differential pressure hole and having a pin member inserted therein to decompress oil. An inner diameter D1 of the decompression portion may be greater than an outer diameter D2 of the pin member. The decompression portion may include an inlet through which oil may be introduced from the high pressure part into the differential pressure hole, and an outlet through which oil from the differential pressure hole may be discharged into the intermediate pressure part.
Abstract:
A scroll compressor is provided having a rotational shaft insertion hole and a fabrication method thereof. The scroll compressor may include a casing; a fixed scroll fixed to the casing; a circulating scroll that forms a compression chamber while performing a circulating movement with respect to the fixed scroll; a rotational shaft having a shaft portion inserted into the fixed scroll, an eccentric portion that penetrates the fixed scroll to be combined with the circulating scroll, and a neck portion having a diameter less than that of the eccentric portion; a fixed bush interposed between the fixed scroll and the shaft portion; and a drive configured to drive the rotational shaft.

Abstract:
The present disclosure relates to a wear-resistant surface treating agent, a manufacturing method thereof, and a compressor using the same. According to one aspect of the present disclosure, the surface treating agent includes an organic solvent, nanodiamond powder and carbon nanotube powder dispersed in the organic solvent, and a PTFE solution mixed with the organic solvent, wherein the organic solvent is an amide-based organic solvent.
Abstract:
A scroll compressor is provided that includes an oil recollecting pump to recollect oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor, and a differential pressure hole formed at a position where it communicates with compression chambers after a suction completion timing, such that oil stored in an inner space of the shell can be supplied into the compression chambers using a pressure difference between a high-pressure inner space of the shell and a low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing an occurrence of a suction loss due to oil.
Abstract:
A rotary compressor including two eccentric portions is provided. The rotary compressor includes: a casing; a cylinder provided within the casing and providing a compression space; a rotational shaft rotatably disposed with respect to the cylinder; a partition plate rotating together with the rotational shaft and dividing the compression space of the cylinder into first and second compression chambers disposed up and down; first and second eccentric portions provided in upper and lower portions of the partition plate and being eccentric in different directions with respect to a rotation center of the rotational shaft so as to rotate together with the rotational shaft; and a driving motor rotatably driving the rotational shaft.
Abstract:
A scroll compressor is provided which is configured such that an arcuate section may be formed from a suction end of a wrap to a first point to increase a suction volume, and a logarithmic spiral section in which a wrap thickness increases may be formed from a second point to a discharge end of the wrap. This may increase a volume ratio of the compressor so as to increase a capacity of the compressor and prevent damage to the wrap due to a high compression ratio operation, thereby enhancing reliability of the compressor.

Abstract:
A scroll compressor includes a case, a fixed scroll having a fixed wrap, and an orbiting scroll having an orbiting wrap coupled to the fixed wrap to define compression chambers. A driving motor has a crankshaft, the crankshaft having one end portion coupled to the orbiting scroll, a main frame and an auxiliary frame fixed onto an inner wall of the case to support the crankshaft, respectively, and a thrust plate having an annular shape and interposed between the auxiliary frame and the crankshaft to support the crankshaft in an axial direction, wherein a plurality of oil channels are formed on a surface of the thrust plate so as to communicate an inside and an outside of the thrust plate with each other.
Abstract:
A scroll compressor includes a fixed scroll having a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to define a first compression chamber between an inner surface of the fixed wrap and an outer surface of the orbiting wrap, and to define a second compression chamber between an inner surface of the orbiting wrap and an outer surface of the fixed wrap. A rotation shaft is provided with an eccentric portion at one end thereof to drive the orbiting scroll. A protruding portion protrudes inwardly from an inner end of the fixed wrap, and contacts the orbiting wrap. A distance between a center of the eccentric portion and a tangent line at a contact point between the protruding portion and the orbiting wrap at an end of the first compression chamber is smaller than a radius of the eccentric portion.
