ABSTRACT:
A muffler for motor compressors comprising a body closed at the lower side by a cover and provided on its frontal wall with a hole through which the refrigerating gas is sucked. The gas introduced into the interior of the body strikes against the rear wall of the body and is diverted toward two narrow passages formed by the lateral internal walls of the body and by vertical walls of an M-shaped element located internally of the body. The inclined walls of the element favor the collection of the oil which has separated from the refrigerating gas and directs it toward an inclined plane which facilitates the discharge of the oil, by gravity, through a groove made in the body of the muffler.
