ABSTRACT:
The dimension of a compressor is decreased, 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) of 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.
