Abstract: | The electrical circuits developed for the purpose of energizing the solenoid valve are examined. These circuits, called the dummy coil method, where energy stored in a dummy coil in the form of a magnetic field is transferred to an energizing solenoid, and the pre-energize method, where the solenoid is electrically energized in advance by taking advantage of the solenoid's attraction force characteristics, are discussed. The results of experiments show that the pre-energize method is highly effective in speeding up the operation of solenoid valves. These experimental results are discussed along with the results of calculations conducted using a mathematical model |
