Compressor

A scroll compressor comprising:

• a housing;
• a motor arranged in the housing;
• a rotating shaft configured to be rotated by the motor;
• an orbital scroll configured to be orbitally moved by the rotating shaft;
• and
• a fixed scroll forming a compression chamber together with the orbital scroll,
• wherein the housing includes
• a rear housing having
• a discharge chamber for accommodating a refrigerant discharged from the compression chamber,
• a discharge port guiding the refrigerant from the discharge chamber to an outside of the housing,
• an introduction port configured to receive an intermediate pressure refrigerant from outside of the housing, and
• an introduction chamber configured to accommodate the refrigerant introduced through the introduction port, wherein the introduction chamber includes:
• an injection valve assembly with a first check valve and a second check valve via which the injection valve assembly is communicated fluidically with the compression chamber;
• wherein the introduction port terminates in the introduction chamber in-between the first check valve and the second check valve when measured along a straight line connecting the first check valve and the second check valve.
