Abstract: A solenoid on-off valve includes a main valve body in a housing. A pilot passage is formed on the main valve body, and a pilot valve body is inserted into the pilot passage so as to open and close the pilot passage. The pilot valve body and the main valve body move in accordance with a plunger which is movable in an opening direction. The plunger and the pilot valve body are coupled by a coupling pin.

Without controlling the drive voltage, it is possible to suppress wasting power such that the driving current of the large current value is generated in the start-up time, and the current value of the driving current is decreased in the holding time.
