Abstract (en)
[origin: EP3751143A1] The present invention is to provide a scroll fluid machine capable of reliably introducing an intermediate-pressure refrigerant during a compression process and improving the efficiency of a compressor. A scroll compressor (1) includes a fixed scroll (18) and an orbiting scroll (19); after sealing of a compression chamber (20) is started, a first region is set in which a volume change of the compression chamber (20) is gradual or substantially constant; a wall body (18b) and a wall body (19b) include a first wall-body inclined part in which heights of the wall bodies (18b) and (19b) continuously increase from an outer peripheral side to an inner peripheral side in a spiral direction; an end plate (18a) and an end plate (19a) include a first end-plate inclined part in which a tooth bottom opposite to a tooth tip of the first wall-body inclined part is inclined according to an inclination of the first wall-body inclined part; and at least a part of the first region is set by positions and shapes of the first wall-body inclined part and the first end-plate inclined part.
