ンプの切替装置。 A pump chamber is formed with a suction valve and a discharge valve on both sides. In a diaphragm pump that alternately repeats suction and discharge operations by introducing and discharging air, the operating shaft is fitted into the shaft hole of the main body and reciprocates, and when it reaches one operating end, it communicates with the operating air chamber. A narrow diameter portion is formed on each side, and the narrow diameter portion is formed using a double pilot type 5
The port spool valves each communicate with the pilot air ports, and the narrow diameter portion on one side communicates with the working air chamber, and when the spool valve is operated, the compressed air in the working air chamber on the one side is exhausted through the spool valve, A switching device for a diaphragm pump configured to simultaneously send compressed air to the working air chamber on the other side through a spool valve.
