溶接によるシール性も確実である。 FIG. 4 shows a rotary compressor equipped with a conventional suction pipe. In Figures 4 to 7, 1
is a rotary compressor, and a rotor 5 and a stator 6 are placed in a closed container 4 consisting of an upper shell 2 and a body shell 3.
It has an electric motor section 7 consisting of a motor section 7, and a compression mechanism section 8 driven by the electric motor section 7. This compression mechanism section 8 includes a shaft 9 directly connected to the rotor 5, a cylindrical cylinder 10, a roller-shaped piston 11 that rotates eccentrically within the cylinder 10, and an upper bearing that is attached above and below in the axial direction of the cylinder 10 and pivotally supports the shaft 9. 1
2 and a lower bearing 13. Reference numeral 14 denotes a suction port, and the suction port 14 is formed through the cylinder 10 from the inner peripheral surface 15 to the outer peripheral surface 16, and an opening hole 17 slightly larger than the inner diameter of the suction port 14 is formed in the body shell 3 at the center of the suction port 14. It is opened on the axis. A copper pipe 18 is fixed to the body shell 3 with a welding material 19. Reference numeral 20 denotes a suction pipe, and an inner tube 25 has a fitting outer circumferential surface 21 formed with a large diameter 22 that fits with the inner diameter of the suction port 14 of the cylinder 10, and a small diameter fitting outer circumferential surface 24 having a small diameter 23 on the same pipe center axis. , an inner circumferential surface 27 having an inner diameter 26 that fits with the small-diameter fitting outer circumferential surface, and an outer tube 29 having an inner surface having a diameter 28 smaller than the inner diameter 26 on the same central axis. The reason why the inner pipe 25 and the outer pipe 29 are not made into one body but is divided into the inner pipe 25 and the outer pipe 29 is because the copper pipe 18 and the suction pipe 32 are made of copper, so the inner pipe 25 and the outer pipe 29 are not integrated. When welding welding material C 33, if the outer tube 29 is made of different metals, the brazing temperature during welding will be different. tube 29
If the material is the same as that of the copper pipe 18 and the suction pipe 32, the welding workability will be improved and the sealability by welding will be more reliable.

That is, the small-diameter fitting outer circumferential surface 24 of the inner tube 25 is inserted into the inner circumferential surface 27 of the outer tube 29 and fixed by the welding material 30. Further, an end 31 of the suction pipe 20 located on the opposite side from the cylinder 10 is welded to the copper pipe 18 with a suction pipe 32 inserted into the suction pipe 20 using a welding material 33, so that the inner and outer parts of the closed container are connected to each other. and is sealed.

If the relationship between L and the length l of the outer tube in the axial direction into which the inner tube is inserted is L>l, there is a circumference with a smaller diameter in the radial direction between the larger diameter of the inner tube and the diameter of the outer tube. Since a concave groove is formed as a surface and the welded portion of the inner tube and outer tube is located within this groove, the welding material for welding the inner tube and outer tube is connected to the inner tube and the compression mechanism. When press-fitting with the suction port of the inner tube, the inner tube does not adhere to the outer circumferential surface of the suction port press-fit side, so the sealing performance does not deteriorate. Therefore, the high-pressure refrigerant gas in the shell will not leak to the suction port from a poorly sealed area and the compression efficiency will not decrease.
