Abstract: A solenoid valve device may include a rod pin; a cylindrical core comprising a magnetic material and arranged around the rod pin; a bobbin comprising resin and arranged to cover a side surface of the cylindrical core; a coil wound around the bobbin; a case comprising a bottom and being cylindrical and having an opening at one axial end thereof, and arranged to accommodate the rod pin, the cylindrical core, the bobbin, and the coil; a nozzle comprising resin and attached to a case opening portion defined at the one axial end of the case; a first a second port each defined in the nozzle; a valve body arranged in the nozzle, and structured to be driven by the rod pin to open or close a communication between the first and second ports; and a tubular metal cover arranged to cover a lateral surface of the nozzle.

Abstract: A solenoid valve device may include a solenoid unit including a rod pin movable; a cylindrical core arranged around the rod pin; a bobbin covering a side surface of the cylindrical core; a coil wound around the bobbin; and a case having a bottom and being cylindrical, having an opening portion at one axial end, and arranged to accommodate the rod pin, the cylindrical core, the bobbin, and the coil; and a nozzle unit. The nozzle unit may include a nozzle having a pin receiving portion and a port opening portion; a first port and a second port; a valve body arranged in the nozzle; and a first metal member fixed to an end portion of the nozzle. The solenoid unit may include a positioning contact portion; and the case may include a fixing portion to fix the first metal member between the positioning contact portion and the fixing portion.
