Abstract
A capacity-controlled scroll compressor for reducing a start shock and improving machinability of a fixed end plate, wherein a high pressure Ph to be guided to a control valve (70) for controlling a control pressure Pm for operating a shuttle valve (60) is introduced from a high pressure passage (72) opening at a discharge port (1c) to reduce a start shock. A bypass hole (52a) and the high pressure passage (72) are constituted by a straight through-hole extending through a cylinder (61) from the outer peripheral portion of a fixed end plate (1a) and consequently, machinability of the fixed end plate (1a) can be improved.
