<p><P>PROBLEM TO BE SOLVED: To improve the adiabatic efficiency within a suction pressure range in a compressor. <P>SOLUTION: A heat insulation member 44 is inserted in a suction chamber 24. A heat insulation member 44 comprises a chamber heat insulation member 441 and passage heat insulation members 442, 443 to cover passage wall surfaces 331, 341 to form a first connecting passage 33 and a second connecting passage 34. A cylindrical member 50 made of an insulating material is loosely inserted into a round passage 45. Connection holes 502, 503 are bored in a peripheral wall of the cylindrical member 50. The connection hole 502 is set to communicate to the first passage 511. The connection hole 503 is set to communicate to the second passage 512. The passage heat insulation members 442, 443 are fitted in the connection holes 502, 503. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
