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, communicating with the second compression chamber, and provided with a second discharge inlet and a second discharge outlet, the second discharge inlet having a larger sectional area than the first discharge inlet. This configuration may prevent a discharge delay in advance in each compression chamber, and thus, preventing a compression loss.

Abstract: A scroll compressor is provided that may prevent an oil-feeding hole from being blocked due to a high pressure refrigerant, which is compressed in compression chambers and introduced into the oil-feeding hole through an oil-feeding slit, by blocking one of both end portions of the oil-feeding slit, adjacent to the compression chambers, when the oil-feeding hole is formed through an outer circumferential surface of a bearing and the oil-feeding slit, which communicates with the oil-feeding hole, is formed on the outer circumferential surface. This may allow for smooth oil supply onto the outer circumferential surface of the bearing through the oil-feeding hole, thereby enhancing a bearing performance. Also, the oil-feeding hole or slit may be formed at a closest position to an oil feeding-required section, not within the section. This may allow for quick oil supply into the oil feeding-required section, resulting in further enhanced bearing performance.

Abstract: A compressor is provided that may include a passage separator provided between an electric motor drive and a compression device to separate a refrigerant passage from an oil passage. The passage separator may include a first partition wall and a second partition wall. The first partition wall may be disposed between an inner circumferential surface of a casing and a discharge hole of the compression device, and the second partition wall may be disposed between the discharge hole and a balance weight. Accordingly, the refrigerant passage may be separated from the oil passage between the compression device and electric motor drive, thereby efficiently recovering oil to an oil storage space.

Abstract: A compressor according to embodiments of the present invention may comprise: a first fluid channel provided to communicate with an oil supply fluid channel so as to allow oil to flow therethrough; a second fluid channel provided to extend from the first fluid channel so as to allow the oil to flow to the outside of a case; a third fluid channel extending from the second fluid channel and provided outside the case; and a main fluid channel extending from the third fluid channel and provided through a fixed scroll or a main frame. Accordingly, the oil is supplied to a compression part by passing along the outside of the case, so that oil can be effectively supplied when a high-pressure operation is performed. Moreover, the present invention may not have a facility such as a pressure reduction pin, so that oil can be effectively supplied when a low-pressure operation is performed.

Abstract: A scroll compressor according to the present disclosure includes a fixed scroll, an orbiting scroll forming first and compression chambers with the fixed scroll, first and second compression chamber oil supply holes formed through the orbiting scroll to communicate with the first compression chamber and the second compression chamber, respectively, wherein when a section in which the first compression chamber oil supply hole is opened toward the first compression chamber is a first oil supply section and a section in which the second compression chamber oil supply hole is opened toward the second compression chamber, a non-overlap section between the first oil supply section and the second oil supply section may be longer than an overlap section between the first oil supply section and the second oil supply section, so as to prevent communication between the first and second compression chambers, thereby suppressing leakage between the compression chambers.
