Summary: | To inhibit vibration transmitted from a compression mechanism to an accumulator.SOLUTION: A joint pipe (43) is fixed to a casing (11). A suction pipe (40) is disposed in the joint pipe (43) and communicates with a suction port (56) of a compression mechanism (50). The suction pipe (40) has: a large diameter part (41) formed at the inflow side of the suction pipe (40) and fixed to an inner peripheral surface of the joint pipe (43); and a small diameter part (42) formed at the outflow side of the suction pipe (40) and having an outer diameter smaller than that of the outer diameter part (41). The joint pipe (43) is formed of a ferrous material. A gap (S1) is formed between an outer peripheral surface of the small diameter part (42) of the suction pipe (40) and the inner peripheral surface of the joint pipe (43).SELECTED DRAWING: Figure 2
【課題】圧縮機構からアキュームレータに伝わる振動を抑制する【解決手段】継手管(43)は、ケーシング(11)に固定される。吸入管(40)は、継手管(43)の内部に配置されるとともに圧縮機構(50)の吸入口(56)に連通する。吸入管(40)は、吸入管(40)の流入側に形成され、継手管(43)の内周面に固定される大径部(41)と、吸入管(40)の流出側に形成され、大径部(41)よりも外径が小さい小径部(42)とを有する。継手管(43)は、鉄系材料で構成される。吸入管(40)の小径部(42)の外周面と前記継手管(43)の内周面との間には、隙間(S1)が形成される。【選択図】図2 |
