Deflection system for alien particles in a refrigeration motor compressor

A muffler system for a refrigeration motor-compressor comprising an upper and lower case, a body mounted within said lower case, a compressor mounted on said body, a motor operatively connected to said compressor, a muffler mounted on said compressor, a tube having a longitudinal axis fixed to said lower case for conveying refrigerant gas into said cases and a V-shaped groove having asymmetrical sides positioned transversely to the longitudinal axis of said tube and along the muffler, one side of said groove closest to said tube being of lesser depth than said side further away from said tube, said side of said groove further away from said tube having an angle of incidence with the longitudinal axis of said tube such that alien particles suspended in the refrigerant flow over said side of said groove of lesser depth to strike the side of said groove of greater depth and upon striking the side of the groove of greater depth causing said particles to rebound away from said muffler, and said groove defining means for conveying refrigerant gas to said compressor.
