<P>PROBLEM TO BE SOLVED: To reduce a pressure loss in a two-stage scroll compressor in which an outside compression part and an inside compression part are arranged. <P>SOLUTION: In the two-stage scroll type compressor having a fixed scroll (52) and an orbiting scroll (54) on one plane and also having the external peripheral side compression part (55A) and the internal peripheral side compression part (55B) by forming a land (53) for connecting wrap parts of the fixed scroll (52) at the fixed scroll (52), the external peripheral side fixed wrap parts (52A, 56) and the external peripheral side orbiting wrap part (54A) are constituted so that two chambers may be merged with each other accompanied by the orbiting motion of the orbiting scroll (54) after the two chambers of the first compression chamber (21A-1) and the second compression chamber (21A-2) are formed, and pressures at the merging of the two chambers may become equal to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
