Patent ID: 8573955

Claim:
A scroll compressor, comprising: a hermetic container configured to receive a refrigerant flowing into and out thereof; a driving device installed in the hermetic container that rotates 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, to compress the refrigerant by an interaction with the orbiting scroll, wherein 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, wherein a sectional area of the discharge outlet portion is larger than a sectional area of the discharge inlet portion, wherein a flow direction length of the discharge outlet portion is larger than a flow direction length of the discharge inlet portion, and wherein a sectional area of the bottleneck section is 0.5 to 0.8 times of the sectional area of the discharge outlet portion to thereby improve a noise suppression effect.
