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.

摘要： A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft. When the turbine is not operated, the top ends of the leaves contact the rotation shaft again due to the elastic restoring force of the leaves.
