A working fluid chamber and a pump chamber are defined on both sides of the pump body through diaphragms interconnected by a center rod, and a suction port is connected to the positive chambers on both sides through suction check valves. In a diaphragm pump in which the discharge port is connected via a discharge check valve and the switching valve alternately controls the supply and discharge of working fluid to the working fluid chambers on both sides, switching pressure reduction is applied to the working fluid chambers on both sides. Opening/closing valves are provided in the switching pressure reducing holes on both sides to open the switching pressure reducing holes in conjunction with the movement of the diaphragm just before the end of the working fluid discharge operation. facing the switching pressure chamber that communicates with the switching pressure reduction hole,
The switching pressure chambers at both ends and the working fluid supply port to the switching valve are connected via an orifice, and the spool is switched by reducing the pressure in one of the switching chambers at both ends of the spool by opening the opening/closing valve. A switching device in a diaphragm pump, characterized in that the working fluid is supplied to the working fluid chamber on the end side of the working fluid discharge operation.
