    • 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.
    • 设置在绕动涡旋件5的后表面上的背压室12通过环形密封件11分成内部区域12a和外部区域12b。环形密封件11的直径d设定为0.5度以上 旋转镜板5a的直径D。 由此,无论施加到内部区域12a的排出压力Pd的大小如何,都可以向绕动涡旋件5施加加力推力。 因此,只有通过排出压力的反压力才能将绕动涡旋件5推靠在固定涡盘4上。 外部区域12b的设定压力Pm减小到接近吸入压力Ps的值,在涡旋式压缩机启动后,压力调节机构20迅速地打开。 由此,润滑油从外部区域12b被供给到吸入空间9而没有时间滞后。
