Scroll compressor

A scroll compressor, comprising:

• a casing;
• an orbiting scroll coupled to a rotary shaft in an inner space of the casing to perform an orbiting motion;
• a non-orbiting scroll engaged with the orbiting scroll to define compression chambers, and provided with a discharge port and bypass holes through which refrigerant in the compression chambers is discharged;
• and
• a back pressure chamber assembly including a back pressure chamber and a floating plate, the back pressure chamber assembly being coupled to a rear surface of the non-orbiting scroll to press the non-orbiting scroll toward the orbiting scroll, wherein a valve accommodating groove is recessed by a predetermined depth into a rear surface of the non-orbiting scroll to accommodate the discharge port and the bypass holes, wherein a valve guide is disposed between the rear surface of the non-orbiting scroll and a rear surface of the back pressure chamber assembly facing the rear surface of the non-orbiting scroll, wherein the valve guide includes bypass valve guide holes into which bypass valves that open and close the bypass holes are slidably inserted in an axial direction, wherein the back pressure chamber assembly further comprises an intermediate discharge port that communicates with the inner space of the casing, and wherein at least one discharge guide passage is defined between the valve guide and the valve accommodating groove, such that the discharge port and the bypass holes communicate with the intermediate discharge port.
