Zusammenfassung: | To restrain an amount of oil flowing in from a refrigerant flow passage formed in an electric motor from becoming excessive or insufficient.SOLUTION: A compressor (10) comprises a casing (20) and an electric motor (60). An internal space (M) of the casing (20) includes a first space (M1) formed on one end side of the electric motor (60), and a second space (M2) formed on the other end side of the electric motor (60). A refrigerant flow passage (100) for allowing the first space (M1) and the second space (M2) to communicate with each other is formed in the electric motor (60). The refrigerant flow passage (100) includes a first flow passage (F1) into which a refrigerant in the first space (M1) or the second space (M2) flows. The first flow passage (F1) is constituted so as to restrain or promote an inflow of oil in the refrigerant.SELECTED DRAWING: Figure 3
【課題】電動機に形成される冷媒流路から流入する油の量が過剰になったり、不足したりするのを抑制する。【解決手段】圧縮機(10)は、ケーシング(20)と電動機(60)とを備える。ケーシング(20)の内部空間(M)は、電動機(60)の一端側に形成される第1空間(M1)と、該電動機(60)の他端側に形成される第2空間(M2)とを含む。電動機(60)には、第1空間(M1)と第2空間(M2)とを連通する冷媒流路(100)が形成され、冷媒流路(100)は、第1空間(M1)又は前記第2空間(M2)の冷媒が流入する第1流路(F1)を含む。第1流路(F1)は、冷媒中の油の流入を抑制又は促進するように構成される。【選択図】図3 |
