Description
以下、装置1の構成及び作動を説明する。
バルブエレメント479bは、リリーフ通路476のうち平面状に弁座476sを形成する段付部分よりも下流側の最下流端476a内に、同軸上に収容されている。かかる収容形態によりバルブエレメント479bは、弁座476sに対する離着座が往復移動により可能となっている。したがって、リリーフバルブ479は、弁座476sからバルブエレメント479bが離座するのに応じて開弁する一方、弁座476sにバルブエレメント479bが着座するのに応じて閉弁する。
以上説明した本実施形態の作用効果を、以下に説明する。
以上、本発明の一実施形態について説明したが、本発明は、当該実施形態に限定して解釈されるものではなく、本発明の要旨を逸脱しない範囲内において種々の実施形態に適用することができる。
