ABSTRACT:
A refrigerant compressor of the type in which a cylinder block and front and rear housings made of an aluminum alloy are fastened together by means of a plurality of bolts made of a ferrous metal and extending through part of the refrigerant gas passage in the compressor and respective bores formed in the front housing, is disclosed. Each of the bolts has a head supported on a bearing surface formed on said housing means, the bearing surface being formed by an annular projection concentric with the bore in the housing. The annular projection is plastically deformed by the bolt when the compressor is assembled, and the bolt head is carried by such deformed annular projection so that an increase in the tightening force is taken up by the elasticity of the projection.
