CA 2074201
A sealing mechanism for a compressor housing is disclosed which seals mating surfaces of a cylindrical portion and a front end plate portion of the compressor housing. The sealing mechanism includes an annular groove formed at an inner end surface of an outer peripheral region of the front end plate portion. The annular groove faces an opening end surface of the cylindrical portion. An O-ring seal element of an elastic material is disposed within the annular groove. The front end plate portion is fixedly attached to the opening end surface of the cylindrical portion by a plurality of bolts so that the O-ring seal element of elastic material is compressedly disposed within the annular groove. Sealing of the mating surfaces of the front end plate portion and the cylindrical portion is accomplished by the elastic deformation of the O-ring seal element within the annular groove. According to the present invention, the annular groove can be formed during casting of the front end plate portion of the compressor housing while maintaining the mechanical strength of the compressor housing at an acceptable value.
