Description
Claims (2)
- 入口室と減圧弁と減圧室とを有し、前記入口室に送入された高圧燃料を、前記入口室から減圧室に通じる導入路に設置した減圧弁で減圧してほぼ一定正圧の気体燃料を保有させる減圧室に導入し、送入された高圧燃料を前記減圧弁に流入させる経路を確保して仕切部材が前記入口室に装入設置され、前記仕切部材により前記入口室の固有振動数を変更した気体燃料の圧力調整器において、前記仕切部材が前記入口室の横断面とほぼ同一の形状、大きさの平板部片に前記導入路とほぼ同径の短管からなる通孔およびこれよりも小径の補助通孔を両端部に位置させて設けてなり、入口室に横断方向に装入して頂壁に押し当てることによって固定したものであることを特徴とする気体燃料の圧力調整器。
- 入口室と減圧弁と減圧室とを有し、入口室に送入された高圧燃料を、前記入口室から減圧室に通じる導入路に設置した減圧弁で減圧してほぼ一定正圧の気体燃料を保有させる減圧室に導入し、送入された高圧燃料を前記減圧弁に流入させる経路を確保して仕切部材が前記入口室に装入設置され、前記仕切部材により前記入口室の固有振動数を変更した気体燃料の圧力調整器において、前記仕切部材が前記入口室の縦断面とほぼ同一の形状であるがこれよりも短い長さの平板部片の一端部に位置させて適宜径の通孔を設けるとともに長辺側の両側縁から脚片をほぼ直角に突出させてなる仕切部材を、前記入口室の導入路から外れた領域の適宜位置に縦断方向に装入し、通孔を設けた側の一端を前記入口室の一つの壁と仕切部材との隙間を形成し、反対端を導入路側の壁に接触させた状態で前記入口室の壁に脚片を圧接させることによって固定したものであることを特徴とする気体燃料の圧力調整器。
