摘要： A back pressure chamber (12) provided on a back surface of an orbiting scroll (5) is divided into an inner region (12a) and an outer region (12b) by an annular seal (11). A diameter d of the annular seal (11) is set 0.5 times or more of a diameter D of an orbiting mirror plate (5a). With this, plus thrust force can be applied to the orbiting scroll (5) irrespective of magnitude of a discharge pressure Pd applied to the inner region (12a). Therefore, it is possible to push the orbiting scroll (5) against the fixed scroll (4) only by back pressure of discharge pressure. A set pressure Pm of the outer region (12b) is reduced to a value close to a suction pressure Ps, a pressure adjusting mechanism (20) is swiftly opened after a scroll compressor is started. With this, lubricant oil is supplied from the outer region (12b) to the suction space (9) without a time lag.

摘要： a First gap 15 in a thrust direction between teeth bottoms of a fixed mirror plate 2b and teeth tips of an orbiting lap 4a, and a second gap 16 in the thrust direction between teeth bottoms of an orbiting mirror plate 4b and teeth tips of a fixed lap 2a are formed such as to gradually increase from an outer peripheral side to an inner peripheral side of a scroll compressor, the first gap 15 is made greater than the second gap 16. Contact surface pressures of the laps 2a and 4a are kept low with respect to pressure deformation, contact pressure of the teeth tips of the fixed scroll part 2 and the teeth bottoms of the orbiting scroll part 4 are equally maintained. With this loads applied to the scroll parts 2 and 4 are equally received by a thrust surface.
