Abstract

PURPOSE:To facilitate switching to unload operation and full-load operation by providing a bypass pipe, through which a suction chamber communicates with an enclosed chamber, in the end plate of a fixed scroll and mounting an opening and closing valve to be interposed halfway the bypass pipe. CONSTITUTION:A pair of bypass holes 1g are provided in an end plate 1a of a fixed scroll 1 in a scroll compressor. Each bypass hole 1g is formed in a position in which it is opened respectively to paired enclosed chambers 5a in the time of maximum volume while closed by a turning scroll lap 2b when the enclosed chamber 5a obtains the volume suited to unload operation decreased smaller by the predetermined volume than the maximum volume by the motion of a turning scroll 2. These bypass holes 1g communicate with a suction chamber 1e by bypass pipes 19 interposing an opening and closing valve 18. The opening and closing valve 18 is controlled so as to close in the time of full-load operation while so as to open in the time of unload operation.
