<p>A diaphragm pump comprising a first diaphragm (5) operated with a driving mechanism such as a crank (2) mechanism, a second diaphragm (9) disposed so as to form an air chamber (8) between the first diaphragm (5) and the second diaphragm (9), and a pump chamber (12) formed by the second diaphragm (9) and a casing (10) or the like, wherein the a pressure in the air chamber (8) is changed by operating the first diaphragm (5) with the driving mechanism and the second diaphragm (9) is deformed by a change of the pressure in the air chamber (12) to perform a pump function. <IMAGE></p> |
