Claims

【実用新案登録請求の範囲】[Scope of utility model registration request]

（１）弁本体内に形成された入口室と出口室とを弁口を
介して互いに洟通し、該入口室内に該弁口を囲んで形成
された弁座と係合可能な弁体を配して該弁体をソレノイ
ドのプランジャに取り付″　　け、該プランジャを゛ル
ノイドコイルへの通電により動作させて該弁口を開閉制
御する電磁弁において、該弁体には該出口室内に伸びる
ロッドの一端を取り付けて該ロッドの他端にダイヤプラ
ムを取り付けるとともに該ダイヤフラムの周辺部を該弁
本体に固定し、該ダイヤフラムを挾んで該出口室と反対
側に形成された室を大気中に開放したことを特徴とした
電磁弁。(1) An inlet chamber and an outlet chamber formed within the valve body are passed through each other via a valve port, and a valve body that can engage with a valve seat formed surrounding the valve port is disposed within the inlet chamber. In the electromagnetic valve, the valve body is attached to a plunger of a solenoid, and the plunger is operated by energizing a solenoid coil to control opening and closing of the valve port. One end was attached, and a diaphragm was attached to the other end of the rod, and the peripheral part of the diaphragm was fixed to the valve body, and a chamber formed on the opposite side of the outlet chamber was opened to the atmosphere by sandwiching the diaphragm. A solenoid valve characterized by:

（２）該出口室側におけるダイヤフラムの受圧面積が出
口室側における該弁体の受圧面積よりも大である実用新
案登録請求の範囲１に記載の電磁弁。(2) The solenoid valve according to claim 1, wherein the pressure receiving area of the diaphragm on the outlet chamber side is larger than the pressure receiving area of the valve body on the outlet chamber side.
