摘要： A surface of a fixed scroll which is opposed to a end plate of an orbiting scroll existing outside of a lap of the fixed scroll is formed with: a substantially annular seal portion which extends such as to have an outer wall surface of the fixed scroll outwardly extending from an inner wall surface of outermost periphery of the lap substantially along the inner wall surface, and which comes into slide contact with the end plate of the orbiting scroll; a substantially annular recess located outside of the substantially annular seal portion; and a recess which is brought into communication with an intake port of the fixed scroll independently from the substantially annular recess. With this, back pressure of the orbiting scroll is increased, and turning-over phenomenon of the orbiting scroll can be suppressed.

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.
