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 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 scroll compressor includes oil in an oil storage space that is brought into direct contact with and stirred with a discharge refrigerant. The scroll compressor includes a fixed scroll, an orbiting scroll coupled to one side of the fixed scroll, and a discharge cover coupled to another side of the fixed scroll and provided with a muffler hole communicating with a refrigerant discharge space and the oil storage space.

Abstract: A compressor includes a driving motor, a centrifugation space, a discharge pipe, a rotary shaft, a compression portion, a pump assembly, and an oil pickup. The centrifugation space is defined inside a case by a downstream side of the driving motor and the case, and enables centrifugation of a compressed refrigerant and a lubricant oil. The discharge pipe can discharge the refrigerant from the centrifugation space outside the case. The rotary shaft is coupled to a rotor of the driving motor and defines an oil supply path. The compression portion is provided at an upstream side of the driving motor and can compress the refrigerant as the rotary shaft rotates. The pump assembly is provided below the rotary shaft and can pump oil as rotated with the rotary shaft. The oil pickup defines an oil supply path between the pump assembly and a low oil space formed inside the case.

Abstract: A hermetic compressor according to the present disclosure may include an oil guide disposed on a rotating shaft between a driving motor and a main frame, the oil guide may include an oil block surrounding a main bearing surface between the main frame and the rotating shaft, and one end of the oil block may radially overlap a shaft support protrusion of the main frame. This can suppress oil returned after lubricating a compression unit from being scattered, thereby reducing a leakage of the oil to outside of a casing through a refrigerant discharge pipe.

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: A scroll compressor is provided that may include a casing; an electric motor drive having a stator fixed within the casing, and a rotor rotatably provided within the stator; a rotational shaft coupled to the rotor to rotate along with the rotor; a compression device disposed at a lower portion of the electric motor drive to receive a rotational force from the rotational shaft and compress a refrigerant; and an oil storage space located within the casing. A plurality of oil discharge paths to allow oil accumulated at an upper portion thereof to be discharged to the oil storage space may be formed on an outer circumferential surface of the compression device to be separated from each other, and an overall cross-sectional area of the plurality of oil discharge paths may be about 2 to about 12% of an inner diameter cross-sectional area of the casing brought into contact with or separated from an outer circumferential surface of the compression device in the compression device.
