Claim 9:
10. A scroll compressor comprising:
a housing;
a motor provided in the housing;
a rotating shaft rotated by the motor;
an orbiting scroll orbitally moved by the rotating shaft;
a fixed scroll forming a compression chamber together with the orbiting scroll; and
a valve mechanism guiding intermediate pressure refrigerant from an outside of the housing to the compression chamber and discharging refrigerant overcompressed in the compression chamber into a discharge chamber, wherein the valve mechanism comprises a first flow path through which the intermediate pressure refrigerant flows, a chamber communicating with the first flow path, a second flow path communicating the chamber and the compression chamber, a third flow path communicating the chamber and the discharge chamber, a first valve opening and closing the first flow path, and a second valve opening and closing the third flow path, wherein the second valve is formed inside the third flow path, wherein the second valve comprises a seat member including a first hole communicating with an inlet of the third flow path and a second hole having a larger diameter than the first hole and communicating with an outlet of the third flow path, a valve member having a diameter larger than the first hole and smaller than the second hole, reciprocating inside the second hole, and communicating and blocking the first hole and the second hole, and an elastic member pressing the valve member toward the first hole.
