1. A scroll compressor comprising:
a fixed scroll;
an orbiting scroll disposed at a first side of the fixed scroll and configured to perform an orbiting motion relative to the fixed scroll and define a compression chamber between the orbiting scroll and the fixed scroll;
a discharge cover disposed at a second side of the fixed scroll that is opposite to the first side of the fixed scroll; and
a casing extending in a first direction and accommodating the fixed scroll, the orbiting scroll, and the discharge cover,
wherein the discharge cover comprises:
a cover bottom surface,
a cover side portion extending from the cover bottom surface toward the fixed scroll, and
a discharge space defined by the cover bottom surface, the cover side portion, and the fixed scroll,
wherein the cover bottom surface and an inner circumferential surface of the casing are spaced apart from each other and define an oil storage space between the cover bottom surface and the casing,
wherein the cover bottom surface defines a muffler hole that is in fluid communication with the discharge space and the oil storage space,
wherein the cover bottom surface is coupled with an oil feeder at a side of the cover bottom surface that is opposite to the fixed scroll, the oil feeder extending away from the fixed scroll, and
wherein the muffler hole is disposed between an outer circumference of the oil feeder and an outer circumferential surface of the cover bottom surface.
