とする三方切換電磁弁。 In a three-way switching solenoid valve that selectively communicates a control port with a supply pressure port or a drain port by energizing or de-energizing an electromagnet, a three-way switching spool valve that can be separated from the solenoid part is housed in a cartridge-type spool barrel. A control port opening is provided in the longitudinal center of the spool barrel, and both ends of the spool valve can be connected to a plunger built into an electromagnet.A spring is inserted only on one side of the spool barrel, and the biasing force is applied to the control port. A three-way switching solenoid valve, characterized in that the valve communicates with either a supply port or a drain port.
