Abstract

See full text

A scroll compressor includes fixed and movable scrolls defining a compression chamber, and a crankshaft. The movable scroll at least partially covers a discharge port formed in the fixed scroll to change a communication area that is a portion of a total area of the discharge port that contributes to communication with the compression chamber. First to third rotation angle positions become larger in order. As the crankshaft rotates from the first to second rotation angle position the communication area increases at a first rate. In the first rotation angle position the compression chamber and the discharge port start communicating with each other. The second rotation angle position is a preliminary discharge interval angle. As the crankshaft rotates from the second to third rotation angle position the communication area increases at a second rate. The second rate of increase is greater than the first rate of increase.
