A counterflow preventing apparatus for a sealed compressor is provided to reduce collision noise when a discharge valve is open and closed and thus to decrease vibration noise of the compressor. A counterflow preventing apparatus for a sealed compressor includes a casing, a compressing unit, a valve housing(810), a valve sheet(820), and a discharge valve(830). The casing has a sealed inner space. The compressing unit is installed in the inner space of the casing to compress sucked refrigerant and discharge it to a discharge space. The valve housing is installed at the discharge space to be in communication with the discharge space. The valve sheet is provided in the valve housing and is formed with a refrigerant through hole(821) at the center thereof. The discharge valve is installed in the valve sheet. |
