    摘要: A rotating shaft is supported by journal bearings that can support without contacting the rotating shaft itself. Then, one end of both shaft end portions of the rotating shaft has a main impeller installed and the other end is provided with a sub impeller. By utilizing a force being generated by rotation of the main impeller, liquid being pumped (fluid being pumped) is sucked in through a suction port and discharged through a discharge port. On the other hand, by utilizing a force being generated by rotation of the sub impeller, fluid is transported to the journal bearings, thereby having the journal bearings support the rotating shaft.

    摘要: A compressor for use in a refrigerator, which has a rotary shaft supported by bearings to be lubricated by a liquid refrigerant and is adapted to permit the rotary shaft to continue rotating for a while after a liquid refrigerant pump is stopped at, for example, a power failure, thereby preventing the bearings from being damaged. To that end the compressor has a reservoir liquid tank for storing high pressure liquid refrigerant to be supplied to the bearing and a gas storage tank for storing high pressure gas. There is a valve system connected between the gas storage tank and the reservoir liquid tank which is operable upon a power failure to supply high pressure gas to the liquid storage tank.
