- 上向きに開口する凹所、前記凹所底面に開口する流体流入通路および前記凹所側面に開口する流体流出通路が設けられたボディと、前記流体流入通路の開口部に設けられた環状の弁座と、付勢部材で下方に付勢されて前記弁座の開口を閉鎖する弁体と、前記ボディの前記凹所に嵌め入れられて前記弁座と前記弁体との間をシールするOリングとを備えており、前記流体流入通路内の流体圧力が所定値以下の場合に、前記弁体が前記弁座に押圧されることで前記流体流入通路が閉鎖されており、前記流体圧力が所定値を超えた場合に、前記弁体が前記流体圧力によって上方に移動させられることで、前記流体流入通路が開放されているリリーフ弁であって、
前記弁座は、前記ボディの前記凹所に着脱可能に嵌め入れられており、前記ボディに、前記Oリングを前記弁座との間で挟持するOリング押さえが固定されており、前記弁体の下端部は、前記弁座の上端面および前記Oリングの一部に当接させられており、
前記ボディと前記弁座と前記Oリングとによって囲まれた空間と前記流体流入通路とを連通する連通路が設けられており、
前記連通路は、前記弁座の底面に設けられた溝を含んでいるリリーフ弁。
