Development of a High-Speed Solenoid Valve. Investigation of the Solenoids.

Development of a solenoid which was used for the high-speed solenoidvalve with a 1 ms switching time is discussed in this paper.First, by using the mathematical model, we quantitatively studied the effects of design particu lars, such as the dimensions of the solenoids and the number of turns of coil, on the switching time. Next, we investigated the suitable and comprehensive conditions that would satisfy given specifications under the various limitations inherent in the solenoid valve's operation.Finally we manufactured the solenoid valves in accordance with the effective methods for performing fast switching, and evaluated their performance.
