Solenoid for electromagnetic valve

摘要

A solenoid (3) for an electromagnetic valve (1A) is provided with a bobbin (8) on which a coil (7) is wound, a movable iron core (5) fitted into an iron core hole (12) of the bobbin (8) and a fixed magnetic pole member (6) for attracting the movable iron core (5). The movable iron core (5) has a main body portion with an even cross-section fitted into the iron core hole, and a flange portion with an even cross-section formed on the distal end of the portion of the main body extending from the iron core hole. A ring (13) has a first distal end side portion (13a) which has a large diameter hole in which the flange portion is fitted and a second proximal end side portion (13b) which has a small diameter hole in which the main body portion is fitted. <IMAGE>
