PROBLEM TO BE SOLVED: To solve a problem that both volume efficiency and motor efficiency decrease by a temperature rise in a hermetic compressor and also durability decreases by the reduction of an oil film thickness of a sliding part.SOLUTION: In a hermetic compressor, a compressing element supported elastically is accommodated in a closed vessel, a discharge pipe is arranged in communication in the closed vessel, and a discharge line is provided which connects the compressing element with an internal discharge pipe. In addition, a discharge chamber is provided at a side nearer the closed vessel than the compressing element so as to lower a temperature of a cylinder and a temperature of a refrigerant gas to be sucked in. |
