Description
Claims (3)
- 固定鉄心が内部に固定されるコイルと、前記コイルの内部に前記固定鉄心と同軸状に軸方向に摺動自在に組み込まれる可動鉄心と、前記可動鉄心の先端に設けられるとともに、弁座に接触して一次側流路と二次側流路との連通開度を調整する弁体と、前記可動鉄心と前記固定鉄心との間に配置され前記弁体を初期位置に付勢するばね部材とを有する比例電磁弁であって、
前記固定鉄心の先端部に凹部を形成する一方、前記可動鉄心の基端部に前記凹部の内周面に隙間を介して対向する外周面が形成された嵌合部を前記可動鉄心の基端部に形成し、
前記固定鉄心の先端部の外周面に先端面に向けて小径となるテーパ面を形成する一方、前記可動鉄心の基端部に前記嵌合部から連なり前記可動鉄心の先端部に向けて大径となるテーパ面を形成し、
前記固定鉄心の前記内周面を先端面に向けて大径となる方向に傾斜させる一方、前記嵌合部の前記外周面を基端面に向けて小径となる方向に傾斜させるとともに、前記外周面の傾斜角度を前記内周面の傾斜角度よりも大きく傾斜させ、
前記弁体が前記弁座に接触し前記流路が閉じられた状態から前記弁体が前記弁座から離れて前記可動鉄心が前記固定鉄心に向けて吸引されるに従って前記内周面と前記外周面の間を径方向に横断する無効磁界を大きくすることを特徴とする比例電磁弁。 - 請求項1記載の比例電磁弁において、前記外周面の傾斜角度は5度であり、前記内周面の傾斜角度は4度であることを特徴とする比例電磁弁。
- 請求項1記載の比例電磁弁において、前記固定鉄心の前記凹部の底面である対向面の深さ寸法は2.5mmであることを特徴とする比例電磁弁。
