Abstract
A joint structure for a refrigerant discharge tube of a hermetic reciprocal compressor having a connecting member fit around the refrigerant discharge tube, the connecting member having a shape corresponding to a connecting hole in a cylinder block, thereby allowing the connecting member to be press-caulked. The refrigerant discharge tube is directly connected to the cylinder block. The connecting hole is multi-layered and may be formed into at least two steps. The connecting member is pre-assembled in the connecting hole by transition-fitting. Accordingly, as the connecting member is press-fit in the connecting hole by a caulking-jig, the connecting member is expanded, and the connecting member is more securely fit in the connecting hole. Since the refrigerant discharge tube is directly connected to the cylinder block, structure is simplified, while the number of assembling steps is reduced. Further, since the connecting member is fit in the connecting hole by the press-caulking instead of the brazing, higher durability is guaranteed and thus, the breakage of the refrigerant discharge tube is prevented.
