SCROLL COMPRESSOR

PURPOSE:To suppress an entrainment phenomenon for return lubricant oil to suction gas as well as to retain a return passage for lubricant oil without the necessity of a large space and by simple construction. CONSTITUTION:A lubricant oil return passage 103 for returning lubricant oil which has lubricated each sliding part to a lubricant oil sump 6 is built up separately from suction gas space. In this case, such a way can be taken that the lubricant oil return passage 103 is formed by outwardly expanding a sealed container 1 in the position of a lubricant oil exhausting hole 40 formed on a frame 8, and a partitioning wall 105 which partitions an oil space from the suction gas space is arranged inside the lubricant oil return passage 103. Instead of the foregoing, the following way may be taken that an oil supply groove extended in a radial direction is formed on the end plate 23 of a swinging scroll 16, and also an annular oil groove to be communicated with the oil supply groove is formed on the end plate 23.
