<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing the yoke for a solenoid valve having a good coaxial accuracy, by simultaneously processing the plunger proximity part and the seating part of a second yoke, by a series of steps of press working.SOLUTION: A solenoid valve 10 is formed of a solenoid 11 having a yoke 12, a core 13, a plunger 14, a coil 17, and the like. The yoke 12, the core 13 and the plunger 14 are formed of a magnetic material. A cylindrical support 36 for supporting the plunger 14 while fitting is formed in the center of the yoke 12. The yoke 12, the body 35 and the support 36 are subjected to drawing by pressing the same material.</p> |
