Abstract
A scroll compressor includes a fixed scroll, a movable scroll revolvable with respect to the fixed scroll, and a crankshaft rotatable to cause the movable scroll to revolve. A discharge port is formed in a first scroll of the fixed scroll or the movable scroll. A cutout portion is formed in a second scroll of the fixed scroll or the movable scroll. The cutout portion formed in the second scroll at least partially passes through a profile of the discharge port formed in the first scroll because of revolution of the movable scroll.
