PROBLEM TO BE SOLVED: To reduce stress strain in inserting a liner into an inlet with respect to a refrigerant intake structure of a hermetic compressor and to curtail heat transfer by brazing.SOLUTION: A decrease in stress strain and curtailment of heat transfer with respect to a compression mechanism part can be achieved by providing a protrusion 8a on an outer diameter of a liner 8 and using it as a hermetically sealed part with an inner diameter surface of an inlet 7. In addition, an outer surface shape of the outer diameter protrusion is made as a spherical shaped protrusion 8b with a proximal point put on an axis, so that misalignment with guide pipes 3 mounted on the inlet 7 and connection aperture 2 of a hermetic vessel 1 can be absorbed for achieving hermetic seal and a degree of assembling margin can be enhanced. |
