ABSTRACT:
A hermetic compressor casing is capable of reducing transmission of vibration to the outside environment by blocking the vibration from the compressor body. The hermetic compressor casing encloses a refrigerant compressing means, which draws in low temperature and low pressure gaseous refrigerant from an evaporator, compresses the drawn refrigerant and discharges the compressed refrigerant. The hermetic compressor casing includes an inner shell enclosing the refrigerant compressing means and having a passageway through which the gaseous refrigerant is drawn in and discharged out, a damping layer enclosing the exterior of the inner shell having a predetermined thickness, and an outer shell enclosing the exterior of the damping layer. As a result, vibration produced from the refrigerant compressing means is damped through the damping layer.
