Description
本発明の実施の形態について、図1乃至図6を参照して説明する。なお、以下に説明する実施の形態は、本発明を実施する上での好適な具体例として示すものであり、技術的に好ましい種々の技術的事項を具体的に例示している部分もあるが、本発明の技術的範囲は、この具体的態様に限定されるものではない。
以上説明した実施の形態によれば、リリーフ流路87が吐出ポート84の始端部841の溝底面84aに開口して形成され、弁体91及びコイルバネ92がリリーフ流路87の開口部87bと回転軸線Oに平行な方向に並んで配置されているので、ポンプ装置1を小型化することができ、車両等への搭載性が向上すると共に、オイルの吐出圧に応じてリリーフ弁9が適切に開弁される。また、弁体91及びコイルバネ92がリリーフ流路87中に配置されているので、弁体91及びコイルバネ92の収容スペースをリリーフ流路87と別に確保する必要がなく、ポンプ装置1をさらに小型化することが可能となる。
以上、本発明を実施の形態に基づいて説明したが、この実施の形態は特許請求の範囲に係る発明を限定するものではない。また、実施の形態の中で説明した特徴の組合せの全てが発明の課題を解決するための手段に必須であるとは限らない点に留意すべきである。
