Claim 9:
10. 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 a compression chamber, and provided with a discharge port and a plurality of bypass holes through which refrigerant in the compression chamber is discharged; and
a back pressure chamber assembly coupled to a rear surface of the non-orbiting scroll to press the non-orbiting scroll toward the orbiting scroll, wherein a block insertion groove is recessed by a predetermined depth into the rear surface of the non-orbiting scroll to accommodate the discharge port and the plurality of bypass holes therein, and a retainer block having at least one bypass valve that opens and closes the plurality of bypass holes is fixedly inserted into the block insertion groove, wherein the at least one bypass valve is fixed to a first axial side surface of the retainer block facing the block insertion groove, wherein the back pressure chamber assembly includes a valve guide groove formed therein such that a discharge valve is slidably inserted therein, wherein the retainer block includes a discharge valve accommodating portion in which the discharge valve is axially supported, wherein the discharge valve accommodating portion includes the discharge guide hole that communicates with the discharge port, and wherein the discharge valve is disposed between the back pressure chamber assembly and the retainer block to open and close the discharge guide hole.
