PURPOSE:To shorten the assembly process by forming a lower hole at the part corresponding to a coolant suction inlet on the side wall of a compressor casing and forming a connecting cylinder body through the burring work and welding a flange formed as an outlet pipe for an accumulator, onto the cylinder body. CONSTITUTION:A rotary type compressor is equipped with a compression element 2 which is formed by accommodating a rotor in rotatable ways into the coolant compression chamber of a cylinder 3 having a coolant suction port 31. When the outlet pipe 7 of an accumulator is connected with the coolant inlet port 31, a lower hole is drilled at the part corresponding to the suction inlet 31 on the side wall of a sealed casing 1, and a cylinder body 12 is formed by bulging out the periphery of the lower hole outwardly by the burring work. While, a flange 71 opposed to the buldged-out top edge surface of the cylinder body 12 is formed on the outlet pipe 7. After the outlet pipe 7 is inserted into the suction inlet 31 from the cylinder body 12, the flange 71 is fixed onto the bulged-out top edge surface of the cylinder body 12 by projection welding. |
