(54) Scroll compressor


(57) A scroll compressor includes a relief port (31A) composed of a plurality of holes for communicating between a compression chamber and a discharge chamber at the outer circumferential side of a discharge port. A plate member (36) is provided corresponding to a portion where at least the relief port (31A) composed of the plurality of holes are opened on an end surface of an end plate of a fixed scroll (16). A single relief flow path (37) integrates the plurality of holes constituting the relief port (31A) into one between the plate member (36) and the end surface of the end plate of the fixed scroll (16), and is communicated with the discharge chamber at the position away from the position of the relief port (31A). A relief valve (34A) is provided at an opening (39) for the discharge chamber in the relief flow path (37).
