1. 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, and wherein the valve mechanism further comprises a cover plate having the first flow path, and a valve plate having the chamber, the second flow path and the third flow path.
