Abstract
PURPOSE: To regulate an electric power supplied to an electromagnetic coil, to con- trive for making the controlling device of the diaphragm pump small and light and also to reduce a temperature rise by adjusting values of a variable resistor VR through a control circuit.
CONSTITUTION: The coils L1, L2 respectively represent the electromagnetic coils 3, 3' and an end of the coil L1 is connected to an AC power source. A circuit formed of a capacitor C1 which is connected in series to a resistor R and the variable resistor VR, is connected between the coil L2 and the AC power source, and also a protection circuit in which a resistor R1 and a capacitor C2 are connected in series is formed in parallel with the above-said circuit to prevent excess currents and excess voltages. The both circuits are connected with each other through the resistor R2 between the resistor R1 and the capacitor C2, and between the variable resistor VR and the capacitor C1. The variable resistor VR is connected on a triac W1 and a gate voltage fed to the triac W2 is controlled by a triac W2.
