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.

Abstract: A compressor includes a discharge guide provided to communicate a discharge port and a bypass port to a discharge cover so that refrigerant discharged from the discharge port and the bypass port is guided to the discharge cover and a middle-pressure chamber formed by the fixed scroll, the back-pressure cover, and the discharge guide. The compressor according to the embodiments guarantees the space in which the bypass valve can be installed by a discharge guide mounted to a discharge portion of the fixed scroll, and at the same time forms the middle pressure portion, resulting in efficiency improvement of the compressor. The compressor according to the embodiments reduces noise and vibration generated from the discharge portion of the fixed scroll by the discharge guide.
