(JA) 回転式圧縮機
Abstract
(EN) A joint pipe (43) is fixed to a casing (11). A suction pipe (40) is disposed inside the joint pipe (43) and communicates with a suction inlet port (56) of a compressing mechanism (50). The suction pipe (40) comprises: a large diameter portion (41) which is formed on the inflow side of the suction pipe (40), and which is fixed to the inner circumferential surface of the joint pipe (43); and a small diameter portion (42) which is formed on the outflow side of the suction pipe (40), and which has a smaller outer diameter than the large diameter portion (41). The joint pipe (43) is made of an iron-based material. A gap (S1) is formed between the outer circumferential surface of the small diameter portion (42) of the suction pipe (40) and the inner circumferential surface of the joint pipe (43).
(FR) L'invention concerne un tuyau de raccord (43) qui est fixé à un boîtier (11). Un tuyau d'aspiration (40) est disposé à l'intérieur du tuyau de raccord (43) et communique avec un orifice d'entrée d'aspiration (56) d'un mécanisme de compression (50). Le tuyau d'aspiration (40) comprend : une partie de grand diamètre (41) qui est formée sur le côté d'entrée du tuyau d'aspiration (40) et qui est fixé à la surface circonférentielle interne du tuyau de raccord (43) ; et une partie de petit diamètre (42) qui est formée sur le côté de sortie du tuyau d'aspiration (40) et qui a un diamètre externe plus petit que la partie de grand diamètre (41). Le tuyau de raccord (43) est composé d'un matériau à base de fer. Un espace (S1) est formé entre la surface circonférentielle externe de la partie de petit diamètre (42) du tuyau d'aspiration (40) et la surface circonférentielle interne du tuyau de raccord (43).
(JA) 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。
