1. A scroll compressor comprising:
a compression mechanism provided in a housing, which includes a fixed scroll and a movable scroll respectively formed at surfaces of mirror plates with spiral laps facing each other,
wherein the movable scroll is revolved and turned with respect to the fixed scroll to thereby compress a working fluid in a compression chamber formed between the laps of both scrolls,
wherein the scroll compressor includes:
a discharge space formed in the housing,
a discharge hole which is formed in the fixed scroll and discharges the compressed working fluid to the discharge space,
a discharge port which discharges the working fluid to the outside of the housing,
a relief passage which communicates the discharge space and the discharge port with each other, and
a differential pressure valve which is provided in the relief passage and opens in accordance with a pressure difference between the discharge space and the discharge port,, wherein the relief passage opens in the discharge space above the discharge hole,
wherein the scroll compressor includes a muffler chamber located between the discharge space and the discharge port and formed in the housing so as to communicate the discharge space and the discharge port with each other,
wherein the scroll compressor includes an oil separator configured in the discharge space,
wherein the working fluid discharged from the discharge hole flows into the muffler chamber after passing through the oil separator, and
wherein the relief passage communicates the discharge space and the discharge port with each other without passing through the oil separator and the muffler chamber.
