Abstract
A scroll compressor is provided with a buffer portion (113b) having an increased diameter at an intermediate part of a discharge port (113). A refrigerant discharged from compression chambers (p) is introduced into the buffer portion (113b), and temporarily stays thereat. Then, the refrigerant is discharged to a discharge plenum (150), thereby reducing a pulsating pressure. Accordingly, noise occurring when the refrigerant discharged from the compression chambers (p) collides with the discharge plenum (150) is reduced, thereby greatly reducing noise of the scroll compressor.
