    • 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.
    • 涡旋压缩机可以包括设置在其固定部件中并且邻近形成在压缩机的绕动涡旋件中的排出孔定位的阻挡部分。 阻塞部分可能在排放操作开始时暂时使排放孔模糊,从而防止排放到排出空间中的制冷剂流回到压缩室中,而不使用单独的止回阀。 这种阻塞部分可以防止由于通常由止回阀产生的噪音导致的总体压缩机噪声的增加。 这种阻塞部分还可以防止由于阀损坏导致的压缩机可靠性水平的降低,并且由于添加阀门而增加了制造成本。
