Abstract
Fluid cooled diaphragms for diaphragm compressors are provided which utilize a multi-layer diaphragm with an upper or gas contacting later, and a bottom or lower layer, which has cooling grooves through which cooling fluid is circulated to reduce the diaphragm temperature. Additionally the upper surface of the diaphragm may be subjected to high loading to indent the surface and produce grooves for gas escape passageways. The gas contacting and grooved layer can be joined over part of the entire surface, or the grooved layer not connected to the other layer. Two or more layers may be used as required.
