Description
本発明は、燃料噴射弁用のソレノイドアクチュエータ(電磁アクチュエータ)ならびに該ソレノイドアクチュエータ用の磁極コアを製造する方法に関する。
請求項1の特徴部に記載の特徴を有する本発明によるソレノイドアクチュエータ、すなわち、磁極コアを備え、該磁極コアは少なくとも1つの磁性の範囲と、少なくとも1つの非磁性の範囲とを有し、前記非磁性の範囲は前記磁性の範囲の磁気的な分離を達成しており、前記磁極コアは一体の構成部分として形成されており、前記磁極コアの前記磁性の範囲と前記非磁性の範囲とは、2成分−金属粉末−射出成形法によって材料接続式に結合されている、つまり原子、分子等の材料の力に基づき結合されていることを特徴とするソレノイドアクチュエータには、従来のものに比べて次のような利点がある。すなわち、この場合、渦電流を効率良く最小限に抑えた磁気回路を有し、ひいては弁の著しく短縮された切換時間を可能にするソレノイドアクチュエータが提供される。このことは本発明によれば、ソレノイドアクチュエータが、少なくとも1つの磁性の範囲と、少なくとも1つの非磁性の範囲とを備えた一体の構成部分として形成されている磁極コアを備えることにより達成される。非磁性の範囲は、磁気的な分離を可能にし、この場合、磁性の範囲と非磁性の範囲との間には、2成分−金属粉末−射出成形法によって材料接続式の結合、つまり原子、分子等の材料の力に基づいた結合が存在している。したがって、ソレノイドアクチュエータの一体の磁気コアを、1回のプロセスステップにおいて短いサイクル時間でかつ少ない部品コストで簡単に大量生産部品として製造することを実現することができる。
−磁性の材料と非磁性の材料とを準備し、
−磁性の範囲と非磁性の範囲との間の材料接続式の結合、つまり原子、分子等の材料の力に基づいた結合を形成するために、磁極コアの非磁性の範囲と磁性の範囲とを、2成分−金属粉末−射出成形法によって製造する。本発明による方法により、一体の磁極コアの製造を高い再現可能性で行うことができるので、燃料噴射弁の切換時間を劇的に低減するソレノイドアクチュエータが提供される。これにより、たとえば自動車における使用時では、著しく少ない燃料量を燃焼室内へ噴射するだけで済む。減じられた噴射量により、エンジンのアイドリング特性が改善される。このことは、エンジンの著しく改善された排ガス特性をもたらす。さらに、本発明による方法は、種々の大きさの複雑な構成部分を製作するためにも、極めて経済的に使用可能となる。
以下に、図1および図2につき、本発明の有利な第1実施形態によるソレノイドアクチュエータならびに該ソレノイドアクチュエータの磁極コアを製造する方法について詳しく説明する。
