20120294748 | Sealed Scroll Compressor for Helium - A sealed scroll compressor for helium having a stationary scroll, an orbiting scroll, and an oil-injection mechanism. The oil-injection mechanism has an oil-injection pipe arranged to pass through a sealed container and connected to an oil-injection port, and the opening of the oil-injection port is arranged at a bottom surface of a groove between ridges formed with the scroll wrap of the stationary scroll in such a manner that a first range of the orbital angle of the orbiting scroll is approximately identical to a second range of the orbital angle of the orbiting scroll, where the oil-injection port is connected to the outer compression chamber while the orbital angle of the orbiting scroll is in the first range, and is connected to the inner compression chamber while the orbital angle of the orbiting scroll is in the second range. | 11-22-2012 |

20140119971 | Sealed Scroll Compressor for Helium - A suction chamber and the oil injection port are linked, under a certain range of revolution angle, via a suction working chamber formed in the radially outer side by a orbiting scroll outer curve and a fixed scroll inner curve under a certain range of revolution angle. An opening of the oil injection port is provided on a bottom surface between teeth of the fixed scroll so that the suction working chamber formed, in a radially inner side, by a orbiting scroll inner curve and a fixed scroll outer curve and the suction chamber are positioned not to be linked with the oil injection port. | 05-01-2014 |
