Abstract
A muffler system for a refrigeration motor-compressor comprising an upper and lower case, a compressor formed by a motor and by a body in which a muffler is fixed, a tube fixed to the lower case conveying the refrigerant gas into the cases, an asymmetric side groove provided along the muffler and positioned with regard to the tube, through which the gas arrives in the case, in such a way that the refrigerant gas passes near a farther side of the groove with an angle of incidence causing the alien particles suspended in the gas to rebound far from the muffler and the gas to be kept by the groove side nearer to the tube and an inlet in the groove for conveying the gas to the compressor cylinder.
