PURPOSE:To aim at the effective cooling of a motor driving part by branching off a suction pipe, drawing a working fluid into a shell of a compressor, to two parts at the outside of this shell, and having the one side opposed to a compressive mechanism part and the other part to the motor driving part, respectively. CONSTITUTION:When a rotor 10 of a motor rotates, a rocking scroll 2 is revolved to a fixed scroll 1 via a main shaft 6, so that a compression space formed between them is compressed. In consequence, refrigerant gas is inhaled in a shell 12 from a suction pipe 16 and then it is discharged out of a discharge pipe 17. In this case, this suction pipe 16 is branched off to two suction pipes 16a, 16b at the outside of the shell 12. The suction pipe 16a on one side is opposed to an inlet port 3 of the fixed scroll 1, while the suction pipe 16b on the other is opposed to a stator 11 of the motor. In addition, refrigerant gas inhaled in the shell 12 from the suction pipe 16b on the other is fed to the compression space 5 from an interconnecting hole 28 after having it passed through the motors 10, 11. |
