Rotary Machine

A rotary fluid machine has an inner rotor 21 and an outer shell 22, arranged so that sealing points on the inside of the shell interact in a sealing arrangement with the outer surface of the rotor, such that in use the relative motion of the rotor to the shell causes fluid to be moved through the machine by means of ducts 27, 30, and ports 28, 29 in the rotor. Preferably the outer surface of the rotor and the inner surface of the shell are in the form of an epitrochoid. In a preferred arrangement the rotor rotates on a first axis and the shell rotates on a second axis offset from the first. Fluid enters the machine by a duct 26 in one side of the rotor shaft and exits via a duct 31 in the other side of the rotor shaft. The machine may be used as a four stroke internal combustion engine or as a fluid compressor.

본 발명은 밀폐형 회전식 압축기의 냉동기유 유로구조에 관한 것이다. 종래에는 상부베어링의 축관통공 내측면에 형성된 냉동기유 유로홈이 상기 축관통공의 하부 끝단에서 상부 끝단까지 관통되게 형성됨에 따른 냉동기유의 과다 토출로 압축기의 습동부 마모량이 증가하고, 냉동기유의 밀봉작용이 부정확하게 이루어짐으로써 기기의 성능 및 신뢰성이 저하되는 문제점이 있었다. 따라서 본 발명은 밀폐용기의 하부측 냉동기유를 회전축 내부로 흡입하여 그 흡입된 냉동기유가 상부베어링의 축관통공을 따라 형성된 냉동기유 유로홈을 따라 이동하도록 구성된 밀폐형 회전식 압축기에 있어서, 상기 상부베어링의 냉동기유 유로홈을 축관통공 하부 끝단에서 상부 끝단의 근접된 위치까지만 형성하고, 그 말단부에는 상기 축관통공과 상부베어링의 외부와 통하는 배출공을 형성하며, 상기 배출공에는 하향되게 냉동기유 파이프를 연결함으로써 기존의 냉동기유 과다 토출로 인한 저온상태에서의 운전 또는 기동시 압축기 내의 냉동기유의 양이 감소되는 것을 방지할 수 있고, 또한 이로인해 회전축으로 공급되어질 수 있는 냉동기유를 충분히 확보할 수 있게 됨으로써 압축기 습동부 마모량을 현저하게 줄일 수 있을 뿐만 아니라 냉동기유의 고유 기능인 압축기내 냉동기유의 밀봉작용이 정확하게 이루어져 기기의 성능 및 신뢰성을 보다 향상시킬 수 있는 효과를 갖게 된다. The present invention relates to a refrigerator oil flow path structure of a hermetic rotary compressor. Conventionally, as the refrigerant oil flow path groove formed on the inner surface of the shaft through-hole of the upper bearing is formed to penetrate from the lower end to the upper end of the shaft through-hole, the amount of wear of the sliding part of the compressor increases due to excessive discharge of the refrigeration oil, and the sealing action of the refrigerator oil is increased. There was a problem that the performance and reliability of the device is reduced by being made incorrectly. Therefore, the present invention is a hermetic rotary compressor configured to suck the refrigeration oil at the lower side of the hermetic container into the rotary shaft and move the suctioned refrigerant oil along the freezer oil flow path groove formed along the shaft through-hole of the upper bearing. The flow path groove is formed only from the lower end of the shaft through hole to the proximal position of the upper end, and at the end thereof, a discharge hole communicating with the outside of the shaft through hole and the upper bearing is formed, and the refrigerator oil pipe is connected downwardly to the discharge hole. It is possible to prevent the amount of the refrigerant oil in the ...

In the scroll compressor according to the present invention, when a lubrication hole is formed through the outer circumferential surface of the bearing and a lubrication groove communicating with the lubrication hole is formed on the outer circumferential surface, the compression chamber is compressed by blocking the ends adjacent to the compression chamber among both ends of the lubrication groove. It is possible to prevent the high-pressure refrigerant flowing into the oil supply hole through the oil supply groove to block the oil supply hole, and through this, the oil is smoothly supplied to the outer peripheral surface of the bearing through the oil supply hole, thereby improving bearing performance. In addition, as the lubrication hole or the lubrication groove is formed at the nearest position avoiding the lubrication required section, the oil is quickly supplied to the lubrication required section, thereby further improving the bearing performance.
