Say, the refrigerant for being stored in low-voltage space 1c is heated by framework 5, motor 20, axle portion 30 and store oil portion 1e oil etc..Cause
This, the temperature of the refrigerant flowed into from suction inlet 1a in low-voltage space 1c is less than the refrigerant having been stored in low-voltage space 1c
Temperature.Therefore, flowed from the refrigerant that suction inlet 1a is flowed into low-voltage space 1c towards downside.Now, by by outage
53 are configured at below the suction inlet 1a of closed container 1 height, and low pressure is flowed into from suction inlet 1a from the oil that outage 53 is discharged
Refrigerant cooling in the 1c of space, therefore temperature further reduces.Therefore, by the way that outage 53 is configured at into closed container 1
Below suction inlet 1a height, the heating inhibition of motor 20 can be further improved, so as to further expand whirlpool
Rotary compressor 100 can operating range.
