Compressor

摘要

An object of the present invention is to decrease the outside dimension of a compressor and to facilitate the installation of the compressor in a limited space by installing a relief valve 50 in such a manner that the relief valve 50 does not protrude from the outer peripheral surface of a closed housing 1 in a compressor in which a compression mechanism incorporated in a closed housing is driven by an external drive source via an electromagnetic clutch. The means for achieving the above object is to assemble the relief valve 50 to the closed housing 1 in such a manner that the relief valve 50 does not protrude from the outer peripheral surface of the housing 1 in order to discharge gas to the outside when the gas pressure in the closed housing 1 increases abnormally.
