Abstract
A muffler for hermetically sealed compressors consisting of a body made of plastic material with two chambers separated by a wall and directly assembled on the compressor cylinder head by means of two lined up small tubes equipped with special sealing means. The danger that the muffler may break loose from the head and possibly rotate on its axis of vertical symmetry is thus avoided.
