Abstract

PURPOSE: To provide a common power source for the solenoid driving and its driving circuit by inserting between the power source and the plunger solenoid a switching means which consists of a part of the driving circuit.
CONSTITUTION: Applying a high voltage level driving signal to the terminal S1 allows the transistor TrQ1 to be conducted to charge the capacitor C1 and TrQ2 to be non-conductive. The signal application to the terminal S1 also caused the TrQ6 and TrQ7 to be conductive. And the TrQ2 non-conductance produces TrQ4 conductance. As a result, the power source +B voltage drives the plunger solenoid PL1 through TrQ4, Q7. As the capacitor is charged. TrQ2 conducts and TrQ4 non- conducts. Since the base of TrQ5 receives the voltage controlled by the Zener diode ZD1, TrQ7 conductance causes TrQ5 conductance. Accordingly, the signal application to the terminal S1 causes TrQ4, Q5 conductance thereby applying a starting voltage to the solenoid PL1 and after a given time, TrQ4 becomes non-conductive to allow a holding voltage application.
