Abstract:
This scroll compressor is provided with a fixed scroll, an orbiting scroll, and an ejection port (18) through which a fluid that has been compressed by the two scrolls is ejected. An end plate of the orbiting scroll is provided with an end-plate side stepped portion formed in such a way that the height thereof increases along a spiral of a spiral wrap (16B) toward a central side thereof, and decreases toward an outer tail end side thereof. A spiral wrap (15B) of the fixed scroll is provided with a wall side stepped portion formed corresponding to the end-plate side stepped portion, in such a way that the height thereof decreases toward the central side of the spiral, and increases toward the outer tail end side thereof. From among a pair of compression chambers (17A, 17B) which face one another across the center of the fixed scroll, a ventral side compression chamber (17A) in which the pressure is high communicates with the ejection port (18) before a dorsal side compression chamber (17B) in which the pressure is low communicates with the ejection port (18).
