<P>PROBLEM TO BE SOLVED: To provide a scroll compressor with high efficiency and less wears by reducing a thrust load (axial supporting force) of a movable scroll. <P>SOLUTION: The compressor includes an inflow passage 15 which supplies high pressure refrigerant gas compressed by both fixed and movable scrolls to a central section surrounded by circular sealing member 6 at the back face of the movable scroll 2, and an outflow passage 17 which makes the refrigerant gas flow out to an outer periphery section of the circular sealing member from the central section surrounded by the circular sealing member, and presses the movable scroll towards the fixed scroll 1 by synthesis pressure of the refrigerant gas at the central section and the outer periphery section of the circular sealing member. An inflow side decompression section 16 and an outflow side decompression section 18 are installed on the inflow passage and the outflow passage, respectively. The minimum passage cross section area of the inflow side decompression section is made 2 to 4 times more than the outflow side passage cross section area. By this arrangement, the sliding loss of the movable scroll becomes smaller and the scroll compressor becomes highly energy efficient. <P>COPYRIGHT: (C)2013,JPO&INPIT |
