Abstract

　プレッシャレギュレータ１は、流入口９を備えた小径流路６と、流体流出口１２を備えた大径流路５とを備えたハウジング２を有する。小径流路６と大径流路５はハウジング２内で連通しており、小径流路６と大径流路５との接続部には、大径流路５に臨んで小径流路６の開口８が形成されている。大径流路５内には、開口８の周縁部１１に当接するボール３が配置され、ボール３はバルブスプリング４にて周縁部１１に圧接される。ボール３の上端部にはバルブガイド１７が取り付けられている。バルブガイド１７には、大径流路５の内周壁５ａと接触するガイド片１７ｂが設けられている。ボール３はバルブガイド１７によって動作が規制され、開弁時等におけるボール３の振動が抑えられる。
