Abstract
A scroll compressor to prevent reverse flow of refrigerant and reducing flow noise. The scroll compressor efficiently distribute refrigerant suctioned into the scroll compressor to a compression chamber and a drive unit. The scroll compressor includes a main body, a fixed scroll fixedly installed in the main body, an orbiting scroll configured to engage with the fixed scroll and perform a relative orbiting motion, and to form a compression chamber with the fixed scroll, a partition plate disposed above the fixed scroll to separate an inside of the main body into a low-pressure portion and a high-pressure portion, a first check valve installed at a discharge port of the fixed scroll to open and close the discharge port, and a second check valve installed on the partition plate to open and close an opening allowing communication between the low-pressure portion and the high-pressure portion.
