PURPOSE:To have stabilized operation of a scroll type fluid machine by furnishing a straight communication hole between the lap side-face of each scroll and the mirror plate surface and by providing a large communication hole in an arbitrary position of the lap without restriction of circumstances of the mirror plate. CONSTITUTION:A straight communication hole 9 is provided being open to the lap 1b side-face of a revolving scroll and a mirror plate surface 1a so as to put a space formed by a stationary and a revolving scroll, i.e. a compression chamber, in communication to the outside. According to this arrangement, in which part of said communication hole 9 is furnished at the lap 1b, the communication hole 9 can be made straight to assure easier operation for processing. Further owing to provision of part of communication hole at the lap 1b, a communication hole 9 with sufficiently large size can be formed in an arbitrary position of the lap 1b of the scroll, so that a sufficient passage can be secured and the operation stabilized. |
