Claims (1)
- 弁体と、前記弁体と別体に構成され、前記弁体を動作させるアンカーと、前記アンカーを磁気吸引力により吸引する固定コアと、を備えた筒内噴射用電磁弁装置に対し、駆動電流を供給させることにより前記弁体を開閉させる駆動回路を備えた電磁弁装置の駆動装置において、
前記駆動回路は、バッテリ電圧よりも高圧の高電圧源による駆動電流を前記電磁弁装置に供給することで前記アンカーを固定コアに吸引させて前記弁体を開弁させた後、前記アンカーと前記固定コアの衝突前に前記電磁弁装置に供給する駆動電流を前記弁体の開弁を保持できない電流値以下まで低下させ、前記衝突前に前記電磁弁装置に供給する駆動電流を前記弁体の開弁を保持できる電流値以上まで上昇させることを特徴とする電磁弁装置の駆動装置。
