ABSTRACT:
A compressor (30) for use in a refrigerator, which has a rotary shaft (33) supported by bearings (39 to 42) to be lubricated by a liquid refrigerant and is adapted to permit the rotary shaft 33 to continue rotating for a while after a liquid refrigerant pump (36) is stopped at, for example, a power failure, thereby preventing the bearings (39 to 42) from being damaged. To that end, the compressor (30) is further provided with a header (52) for storing a predetermined amount of a high-pressure liquid refrigerant, and with check valves (51, 54 and 56) for maintaining the internal pressure of this header (52) at a high pressure for a predetermined time period after a power failure occurs.
