PURPOSE: To reduce the vibration and noise of a compressor as well as to abate the noise out of a refrigerator by joining a refrigerant gas discharged out of the side of an electric motor for a compressive mechanical part with that discharged out of the opposite motor side at this opposite motor side, and having it discharged out of the opposite motor side.
CONSTITUTION: A refrigerant gas compressed in a first cylinder 7 is discharged to the side of a main bearing 6 as in an arrow and, after it is deadened by a first silencer 16 at the side of a main shaft 6, passing through an interconnecting hole 17 interconnecting throse of main bearing 6, first cylinder 7, partition plate 8, second cylinder 9, and a sub-bearing 10, then it arrives at a second silencer 18 at the side of this sub-bearing 10. Subsequently at the second silencer 18, the refrigerator gas is joined together with that discharged to the side of the sub-bearing 10 after being compressed in the second cylinder 9 and thus it is deadened. The joined refrigerator gas passes through a discharge port 19 and it is emitted to the inside of a hermetically sealed vessel 1, and discharged to the outside of a compressor from a discharge pipe 20.
