PURPOSE:To reduce the numbe of parts items in clamping metal devices as well as to make improvements in assembling operatability, by unitizing an accumulator at the suction side, a clamping metal fitting and another metal fitting for clamping a refrigerant injection pipe as one body. CONSTITUTION:A clamping metal fitting 21, unitizing a metal fitting to set an accumulator at the suction side and another metal fitting to set a refrigerant injection pipe 18 as one body, is stuck fast to a closed vessel 20. The accumulator is attached to a contact face 21a of this metal fitting while an injection pipe to a fixed part 21d respectively, with setting bands 3 and 22. Therefore, it will to that a setup of the closed vessel and the clamping fitting is welded together at a one spot alone, so that assembling operation becomes very easy. |
