Claims

[Claims for Utility Model Registration] (1) A fixed column and a movable plunger are arranged inside a solenoid to face each other in the axial direction, and the plunger is displaced in the axial direction by the magnetomotive force of the solenoid. The electromagnetic valve is a solenoid valve that drives a valve body that is locked to a plunger, and the cylindrical body is inserted into the solenoid and accommodates the opposing fixed column and the plunger, and is made of a non-magnetic material. A solenoid valve comprising a first annular member surrounding an opposing portion, and a plurality of second annular members made of a magnetic material and facing each other with the first annular member sandwiched in the axial direction. (2) The electromagnetic valve according to claim 1, wherein the first annular member constituting the cylindrical body is non-conductive. (3) The electromagnetic valve according to claim 1, wherein the cylindrical body is a bobbin around which a conducting wire constituting the solenoid is wound. (4) Utility model registration claim 1, characterized in that the cylindrical body is a housing that is inserted into a bobbin around which a conductive wire constituting the solenoid is wound and that guides the fixed column and the plunger. Solenoid valve described in section.
