Description
すなわち、この装置では、図1及び図2で示したものと同様に、磁極部材10,12、インダクションコイル16,18、シリンダ22、ピストン24、アーマチュア28、コイルバネ30、チェックバルブ32,34、流体入口38及び流体出口40を有するハウジング36を備えている。このような電磁往復動流体装置は、例えば、特許文献1に開示されている。
すなわち、一般的には、磁気回路部材41は、磁極部材10,12と同じ厚さとされ、それに応じて幅も決定されるが、そのようにして構成された磁気回路においては、磁気回路部材41と磁極部材10,12との付け根の部分では磁束集中が見られ、この磁束集中により磁気抵抗が増加し、当該装置の効率の低下の原因となっていた。
ピストンロッド、及び、該ピストンロッドに取り付けられた磁性アーマチュアを備えるピストンであって、当該ピストンロッドの長手方向軸線に沿って往復動可能とされたピストンと、
前記軸線に対して直交する方向で間隔をあけた一対の磁極部材を備えた磁気回路であって、間歇的に励磁されて磁極部材間に磁力を生起し、前記アーマチュアを吸引して前記ピストンを前記軸線方向で駆動する磁気回路と、
を備える磁気往復動流体装置において、
前記磁気回路が、環状磁気回路部材を有し、前記磁極部材が該環状磁気回路部材の内周面の対向する部分から突出するようにされ、該磁極部材及び環状磁気回路部材が前記軸線方向で一定の厚さとされると共に、
当該磁気回路が更に、環状磁気回路部材に重ね合わされるように設定されて磁気回路の一部を構成する第1追加磁気回路部材を備えることを特徴とする磁気往復動流体装置を提供する。
第1及び第2ハウジングが、前記環状磁気回路部材及び第1追加磁気回路部材を、前記軸線方向で挟着するように設定され、内部に前記ピストンを収納するようにすることができる。
