    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 scroll compressor, whose back pressure is easily controlled and compression efficiency is high, is provided. The scroll compressor includes a plurality of compression chambers formed by engaging a fixed-scroll wrap and an orbiting-scroll wrap, and a back pressure chamber formed at an opposite side of the orbiting-scroll wrap of a orbiting-scroll. The scroll compressor additionally includes a high pressure chamber and a middle pressure chamber, which are formed by dividing the back pressure chamber using a seal. Moreover, the scroll compressor includes a first path for supplying lube oil from the high pressure chamber to the middle pressure chamber, and a second path for supplying the lube oil from the middle pressure chamber to an suction chamber of the compression chambers. The first path is intermittently opened by orbit of the orbiting-scroll.

The compression mechanism includes a stationary impeller component having a stationary impeller, a rotary impeller component having a rotary impeller for engaging with the stationary impeller to define a plurality of spaces to be compressed between them, a crank shaft rotatably driving the rotary impeller component, a bearing component for supporting the crank shaft, a self-rotation restricting component for restricting the self-rotation of the rotary impeller component but allowing only its forced rotation, a thrust bearing for supporting the rotary impeller component axially biased to it, and a partition frame component interposed between the stationary impeller and bearing components. The partition frame component is interposed between the upper and lower vessels at their respective open ends so that both vessels may be completely sealed through the partition frame component by welding its entire outer periphery.
