Abstract

A diaphragm pump e.g. for vacuum generation, includes a diaphragm (5) secured at its periphery (13) to the pump casing (2), and in its central region to the head (8) of a connecting rod (4), by means of a fastening plate (9). Between the regions where the diaphragm (5) is secured, is a free region (14) where it is subject only to bending stresses. To avoid the substantial overlapping of bending and compressive stresses where the diaphragm (5) is secured, in at least one, and preferably both of the regions there is provided a clamped region (A) where the diaphragm (5) is subjected to compressive stresses, and a guide region (B) between the clamped region (A) and free region (14) where flexure of the diaphragm (5) is restricted, but compressive stresses are substantially lower than in the clamped region (A), preferably being eliminated. Between the clamped region (A) and the guide region (B) there may be a transitional region (C) over which the compressive stresses decrease progressively. <IMAGE>
