Abstract
A scroll compressor includes a discharge port at a central portion, and a pair of scrolls that define two compression chambers continuously moving toward the discharge port, and a plurality of bypass portions defined at with an each interval along a compression path of each compression chamber. Compression gradients of the both compression chambers are different from each other. An interval between a bypass portion closest to the discharge port and another bypass portion is defined as a first interval. The first interval of a the bypass portion belonging to a compression chamber having a relatively larger compression gradient is smaller than that of the bypass portion belonging to the other compression chamber.
