Abstract

A diaphragm muffler for quiet operation of a compressor imparting an above atmospheric pressure stream and a below atmospheric pressure stream. The diaphragm muffler including a diaphragm pressure chamber receiving the above atmospheric pressure stream; a diaphragm vacuum chamber receiving the below atmospheric pressure stream; and a flexible diaphragm dividing the diaphragm pressure chamber receiving the above atmospheric pressure stream from the diaphragm vacuum chamber receiving the below atmospheric pressure stream, whereby the above atmospheric pressure stream and the below atmospheric pressure stream cancel each other out via the flexible diaphragm.
