Abstract
Provided is an efficient scroll compressor capable of suppressing deformation of a fixed scroll during operation. The scroll compressor includes: a fixed scroll (30) including a fixed-side end plate (32) and a spiral fixed-side wrap (34) protruding from a front surface (32a) of the fixed-side end plate; a movable scroll (40) including a spiral movable-side wrap (44) combined with the fixed-side wrap to form a compression chamber (Sc); and a cover member (60) disposed in a high-pressure space on a rear surface (32b) side of the fixed-side end plate and attached to the fixed scroll. The fixed-side end plate includes a compression chamber adjacent portion (33) at which the front surface of the fixed-side end plate faces the compression chamber. The compression chamber adjacent portion includes a high-pressure adjacent portion (33a) disposed at a central portion of the compression chamber adjacent portion, and an intermediate- and low-pressure adjacent portion (33b). At the high-pressure adjacent portion, the front surface of the fixed-side end plate faces a high-pressure compression chamber. The intermediate- and low-pressure adjacent portion is disposed on the outer side of the high-…
