Scroll compressor

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.

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.
