Abstract: A scroll compressor is disclosed which prevents leakage of refrigerant from a compression chamber and abrasion of bearings between a rotating shaft and an orbiting scroll by reducing the tilting angle of the orbiting scroll, because the allowable bearing angle is equal to or larger than the tilting angle, where the allowable bearing angle θ refers to the maximum angle at which the orbiting scroll is tilted with respect to the rotating shaft, and the tilting angle β refers to the angle at which the orbiting scroll is tilted with respect to the plate.

Abstract: A scroll compressor includes an oil circulation pipe having one end inserted through a casing to be connected to an oil storage space inside the casing and another end connected to a suction passage for supplying refrigerant from outside of the casing to a compression chamber, an oil circulation valve disposed between the both ends of the oil circulation pipe to selectively open or close the oil circulation pipe, and a controller to control an opening or closing operation of the oil circulation pipe to reduce or eliminate frictional loss due to a shortage of oil by adjusting an oil level of the oil storage space at an initial operation.

Abstract: There is disclosed a scroll compressor according to the present disclosure in which a discharge port is formed at a central portion thereof, and a pair of two compression chambers continuously moving toward the discharge port are formed, and a plurality of bypass portions are formed at each interval along a movement path of each compression chamber in the both compression chambers, and compression gradients of the both compression chambers are formed to be different from each other, wherein when an interval between a bypass portion closest to the discharge port and another bypass portion adjacent to the bypass portion among the bypass portions of each compression chamber is defined as a first interval, respectively, a first interval of a second bypass portion belonging to a compression chamber having a relatively larger compression gradient is formed to be smaller than that of a first bypass portion belonging to the other compression chamber between the both compressor chambers.

Abstract: A scroll compressor is provided that may include a first compression chamber, a second compression chamber separated from the first compression chamber, and having a greater compression ratio than the first compression chamber, a first discharge port that communicates with the first compression chamber and provided with a first discharge inlet and a first discharge outlet, and a second discharge port separated from the first discharge port, that communicates with the second compression chamber, and provided with a second discharge inlet and a second discharge outlet, the discharge outlet of at least one of the first discharge port or the second discharge port may have a larger sectional area than the discharge inlet. Accordingly, a discharge delay in each compression chamber may be prevented in advance, thereby suppressing compression loss.

The first discharge inlet and the first discharge outlet may have a same cross section, and the second discharge inlet and the second discharge outlet may have a same cross section. Accordingly, a discharge delay in each compression chamber may be prevented in advanced, and thus, compression loss may be suppressed.

Abstract: A scroll compressor is provided that may include a casing configured to contain oil at a lower portion thereof; a drive motor provided at an inner space of the casing; a rotational shaft coupled to a rotor of the drive motor, and having an oil supply passage in order to guide the oil contained in the casing to an upper side; a frame provided below the drive motor; a fixed scroll provided below the frame, arid having a fixed wrap; and an orbiting scroll provided between the frame and the fixed scroll, having an orbiting wrap to form a compression chamber by being engaged with the fixed wrap, and having a rotational shaft coupling portion to couple the rotational shaft thereto in a penetrating manner. One or more oil dimples may be formed at a peripheral end surface positioned between an inner circumferential portion and an outer circumferential portion of the rotational shaft coupling portion. With such a configuration, as oil may be smoothly supplied to an end surface of the orbiting wrap near the rotational shaft coupling portion, abrasion may be prevented.

Abstract: A scroll compressor is provided that may include an orbiting scroll having an orbiting wrap, and which performs an orbiting motion; and a fixed scroll having a fixed wrap to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the orbiting wrap. In a state in which the orbiting scroll and the fixed scroll are concentric with each other, when a distance between the orbiting wrap and the fixed wrap is defined as an orbiting radius, there exists an offset section having an interval larger than the orbiting radius, between a side surface of the orbiting wrap and a side surface of the fixed wrap which faces the orbiting wrap. With such a configuration, even if the fixed scroll or the orbiting scroll is transformed due to thermal expansion, interference between the fixed wrap and the orbiting wrap at a portion having a large transformation amount may be prevented. This may prevent a frictional loss or abrasion between the fixed wrap and the orbiting wrap. Further, this may restrict or minimize a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction chamber, resulting in enhanced compression efficiency.

Abstract: A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented.
