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.

Description

technical field [0001] The present invention generally relates to a hermetic reciprocating compressor, and more particularly, to a connection structure for a refrigerant discharge pipe as a passage for compressing refrigerant. Background technique [0002] Such as figure 1 As shown, a conventional hermetic reciprocating compressor includes a motor unit 20 and a compression unit 30 within a casing 10 consisting of an upper casing 11 and a lower casing 12 . The compression device part 30 is driven by power transmitted from the electric device part 20 to compress the refrigerant. [0003] The electric device part 20 in the case 10 includes a fixed stator 21, a rotor 22 provided for rotation relative to the stator 21, and a rotating shaft 23 press-fitted in the rotor 22 and having an eccentric portion 23a at one end thereof. [0004] The compression device part 30 includes a cylinder block 31 having a compression chamber 31a; a cylinder head 40 mounted on the cylinder block 31...
