Abstract
A scroll compressor is provided that includes a hermetic container into and out of which a refrigerant flows, a driving device installed in the hermetic container to rotate a rotation axis, an orbiting scroll fixed to the rotation axis and rotated with the rotation axis, and a fixed scroll fixed to the hermetic container and engaged with the orbiting scroll to define a compression chamber, in which the refrigerant is compressed, by an interaction with the orbiting scroll. A discharge hole of the fixed scroll comprises a discharge inlet portion through which high pressure refrigerant flows in, a discharge outlet portion through which the high pressure refrigerant flows out, the discharge outlet portion being eccentric to the discharge inlet portion, and a bottleneck section through which the discharge inlet portion and the discharge outlet portion communicate with each other. The scroll compressor reduces pulsation noise of the refrigerant to improve noise performance.
