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. A wrap thickness of the fixed wrap may be greater than a wrap thickness of the orbiting wrap within a range which forms the suction chamber. With such a configuration, even if the fixed scroll or the orbiting scroll is thermally-expanded, a transformation of the fixed wrap at a suction side may be prevented. This may prevent a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction side, thereby enhancing compression efficiency.

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 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.

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 translation: 提供一种涡旋压缩机，其可以防止供油孔由于在压缩室中被压缩并通过供油槽引入给油孔的高压制冷剂而被阻塞，通过阻塞两端 在供油狭缝的与压缩室相邻的部分，当供油孔通过轴承的外周面形成时，与供油孔连通的供油槽形成在 外圆周表面。 这可以允许通过供油孔向轴承的外周表面供油平稳，从而提高轴承性能。 此外，供油孔或狭缝可以形成在与供油需要部分最接近的位置，而不在部分内。 这可能允许快速供油到供油需要部分，从而进一步提高轴承性能。

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.
