Abstract
Diaphragms for pumps, compressors and the like are provided with a substantially flat planar end face confronting the media being pumped or compressed and have an outer peripheral zone for clamping the circumference of the diaphragm in the pump or compressor housing, an annular intermediate flexing or bending zone adjacent the clamping area, and a central thickened work zone with the flexible bending zone increasing in thickness toward the central working zone. The bending or flexing of the annular intermediate zone is limited to one side of the flat planar end face and the bending stresses are minimized.
