Claims

[Scope of utility model registration request]

The central parts of multiple diaphragms are interconnected,
By supplying and discharging working fluid to and from the working fluid chambers defined on one side of each diaphragm to operate each diaphragm, the volume of the pump chambers defined on the other side of each diaphragm is changed. In a diaphragm pump, three or more diaphragms are provided at equal distances from the center of the pump, and the centers of the three or more diaphragms are interconnected by a crank mechanism provided at the center of the pump. A diaphragm pump characterized in that a crankshaft of the mechanism is provided with a rotary valve for switching and controlling the working fluid supplied to and discharged from each of the working fluid chambers.
