Claim 2:
3. A scroll compressor comprising:
a housing;
a motor provided in the housing;
a rotating shaft rotated by the motor;
an orbital scroll orbitally moved by the rotating shaft;
a fixed scroll forming a compression chamber together with the orbital scroll;
an injection flow path guiding an intermediate pressure refrigerant from an outside of the housing to the compression chamber; and
an injection valve assembly opening and closing the injection flow path, wherein the injection valve assembly comprises:
a cover plate having an inlet through which the intermediate pressure refrigerant is introduced;
an injection valve opening and closing the inlet; and
a valve plate having an outlet guiding the refrigerant that has passed through the injection valve toward the compression chamber, wherein the housing comprises a rear housing including a discharge chamber accommodating the refrigerant discharged from the compression chamber, a discharge port guiding the refrigerant in the discharge chamber to the outside of the housing, an introduction port through which the intermediate pressure refrigerant is introduced from the outside of the housing, and an introduction chamber accommodating the refrigerant introduced through the introduction port, wherein the cover plate covers the introduction chamber, wherein the inlet communicates with the introduction chamber, wherein the valve plate is coupled to the cover plate from an opposite side of the introduction chamber with respect to the cover plate, wherein the injection valve is interposed between the cover plate and the valve plate, wherein the cover plate comprises an upper surface of the cover plate opposite to the introduction chamber, and a lower surface of the cover plate opposite to the valve plate and the injection valve, wherein a first sealing member is interposed between the upper surface of the cover plate and an annular wall, and wherein an injection valve seating groove engraved from the lower surface of the cover plate is formed on the lower surface of the cover plate to seat the injection valve.
