<p>PROBLEM TO BE SOLVED: To provide a compressor which suppresses heat receiving into a low temperature low pressure suction gas by suppressing a temperature rise of an inner wall of a suction hole and a cylinder inner diameter wall surface forming a suction chamber, and which has high volumetric efficiency.SOLUTION: Extension parts 7a and 8a extending to a half or more of a suction part 5a of a cylinder 5 are provided at least one of an upper bearing 7 and a lower bearing 8. By bringing the extension parts 7a and 8a close to the suction part 5a, the upper bearing 7 and the lower bearing 8 cover the suction part 5a of the cylinder 5, and a high temperature outside atmosphere coming into contact with a compression mechanism part 4 and the suction part 5a of the cylinder part 5 are separated. Heat receiving in a low temperature low pressure suction gas is suppressed by suppressing a temperature rise of an inner wall of a suction hole 12 and an inner diameter wall surface of the cylinder 5 for forming a suction chamber 9, and volumetric efficiency of a compressor can be improved.</p> |
