Abstract
【解決手段】磁気回路を形成するバルブボデー12は、アーマチャ13が収納される第1筒部12aおよびコイル31が収納される第2筒部12bを有し、第1筒部12aの外周面には、アーマチャ13の外周面に対向する位置に凹部128が環状に設けられ、この凹部128の最小外径は、第2筒部12bの内径よりも小さくなっている。このようにすれば、第1筒部12aにおけるアーマチャ13に対向する面から第2筒部12bに磁束が流れる際に、遠回りしようとする磁束の流れが凹部128によって阻止されるため磁路が短くなり、吸引時の応答性を向上させることができる。
【選択図】図2
Description
本発明の第1実施形態について説明する。図1は本発明の第1実施形態に係る電磁駆動装置を備える蓄圧式燃料噴射装置の全体構成を示す図である。この燃料噴射装置は、高圧燃料が蓄圧される略円筒状の蓄圧器1を備えており、蓄圧器1には、図示しない内燃機関(より詳細には、ディーゼルエンジン)の各気筒毎に設けられる複数の燃料噴射弁2が接続され、蓄圧器1内に蓄圧される高圧燃料が各燃料噴射弁2から対応する気筒に噴射されるようになっている。燃料噴射弁2の開弁時期および開弁時間は、図示しない電子制御ユニット(以下、ECUという)によって制御される。
本発明の第2実施形態について説明する。図5(a)は本発明の第2実施形態に係る減圧弁の構成を示す断面図、図5(b)は図5(a)の減圧弁における磁路断面を示す図である。第1実施形態と同一もしくは均等部分には同一の符号を付し、その説明を省略する。
