Abstract
A scroll compressor may include a blocking portion provided in a fixed component thereof, and positioned adjacent to a discharge hole formed in an orbiting scroll of the compressor. The blocking portion may temporarily obscure the discharge hole upon initiation of a discharging operation, thereby preventing refrigerant discharged into a discharging space from flowing back into a compression chamber, without the use of a separate check valve. Such a blocking portion may prevent an increase in overall compressor noise due to noise typically generated by a check valve. Such a blocking portion may also prevent degradation in compressor reliability levels due to valve damage and increases in fabricating costs due to the addition of the valve.
