Claim 15:
16. 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 valve plate comprises an inclined space serving as a retainer of the injection valve and accommodating the refrigerant flowing in through the inlet, wherein the inlet comprises a first inlet; and a second inlet formed independently of the first inlet, wherein the injection valve comprises a first head opening and closing the first inlet, a first leg supporting the first head, a second head opening and closing the second inlet, a second leg supporting the second head, and a periphery supporting the first leg and the second leg, wherein the inclined space comprises a first inclined space serving as a retainer of the first head and accommodating the refrigerant flowing in through the first inlet, and a second inclined space serving as a retainer of the second head and accommodating the refrigerant flowing through the second inlet, wherein the compression chamber comprises an outer compression chamber formed by an outer circumferential surface of an orbiting wrap of the orbital scroll and an inner circumferential surface of a fixed wrap of the fixed scroll, and an inner compression chamber formed by an inner circumferential surface of the orbiting wrap and an outer circumferential surface of the fixed wrap, and wherein the outlet comprises a first outlet guiding the refrigerant of the first inclined space to the outer compression chamber, and a second outlet guiding the refrigerant of the second inclined space to the inner compression chamber.
