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.

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.
摘要翻译：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设定为旋转镜板（5a）的直径D的0.5倍以上。由此，无论施加到内部区域（12a）的排出压力Pd的大小如何，都可以向绕动涡盘（5）施加加力推力。因此，只有通过排出压力的反压力才能将动涡旋盘（5）推靠在固定涡旋盘（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迅速地打开压力调节机构20。由此，润滑油从外部区域（12b）供给到吸入空间（9）而没有时间滞后。
