PROBLEM TO BE SOLVED: To provide a solenoid valve capable of effectively eliminating or restricting occurrence of poor operation caused by adhesion of a main valve body against a valve holder.SOLUTION: A solenoid valve 40 comprises: a valve main body 54 having a valve chamber 58, an inlet port 61, an outlet port 62, a valve seat 59 and a valve holder 72; a main valve body 67 movably arranged in the valve chamber; and a solenoid coil 51. Electrical energization control for the solenoid coil may provide a state in which the main valve body abuts against the valve seat to shut off between the inlet port and the outlet port and a state in which the main valve body abuts against the valve holder to communicate between the inlet port and the outlet port. An inner side of an end surface of the main valve body 67 abutted against the valve holder 72 is formed with a deletion part to have a relation of an area Sd at the inner diameter of the end surface of the main valve body>an area SD of an outer shape at the end surface of the main valve body×0.7.SELECTED DRAWING: Figure 2
【課題】主弁体が弁ホルダに張り付くことによる動作不良の発生を効果的に解消若しくは抑制することができる電磁弁を提供する。【解決手段】電磁弁40は、弁室58、流入口61、流出口62、弁シート59、弁ホルダ72を有する弁本体54と、弁室内に移動可能に配置された主弁体67と、電磁コイル51を備える。電磁コイルへの通電制御により、主弁体が弁シートに当接して流入口と流出口の間を遮断した状態と、主弁体が弁ホルダに当接して流入口と流出口の間を連通させた状態とする。弁ホルダ72に当接する主弁体67の端面の内側に削除部を形成し、主弁体の端面の内径の面積Sd>主弁体の端面の外形の面積SD×0.7とする。【選択図】図2
