Description
以下、本発明の一実施形態にかかる積層型圧電素子について詳細に説明する。図1Aは本実施形態にかかる積層型圧電素子を示す斜視図である。図1Bは、図1Aに示す積層型圧電素子の内部構造を説明するために積層型圧電素子の一部分を示した分解斜視図である。図2は本実施形態にかかる積層型圧電素子の一部を拡大した断面図である。
図4は、本発明の一実施形態にかかる噴射装置の概略を示す断面図である。図4に示すように、本実施形態にかかる噴射装置は、一端に噴射孔33を有する容器31の内部に収納された上記実施形態に代表される本発明の積層型圧電素子を備えている。容器31内には、噴射孔33を開閉することができるニードルバルブ35が配設されている。噴射孔33には燃料通路37がニードルバルブ35の動きに応じて連通可能に配設されている。この燃料通路37は外部の燃料供給源に連結され、燃料通路37に常時一定の高圧で燃料が供給されている。従って、ニードルバルブ35が噴射孔33を開放すると、燃料通路37に供給されていた燃料が図示しない内燃機関の燃料室内に噴出されるように構成されている。
結果は表1に示すとおりである。
