- 圧縮空気の流入口と流出口とが上部に設けられたジョイント部と、排水孔が形成された継手が底部に設けられ前記ジョイント部に取り付けられる容器とを備え、前記流入口から前記流出口に流れる圧縮空気中から分離された液体を自動的に排出する常閉形フロート式オートドレンであって、
上端に空気流入孔が形成され、前記排水孔に連通させて前記継手に取り付けられる支持筒体と、
前記容器内のフロート室と前記排水孔とを連通する通路が形成され前記支持筒体内に設けられる受け台と、
前記支持筒体の内面に摺動自在に装着され前記支持筒体内に前記空気流入孔に連通する圧力室を区画するピストンと、当該ピストンと一体に設けられ前記継手の前記排水孔の位置に設けられたシール部材に接触するとともに前記排水孔を開閉する開閉部とを有するピストン部材と、
前記容器の前記フロート室内に上下動自在に配設され、前記容器内に溜まった液体による上昇移動によって前記空気流入孔を開いて前記圧力室内に圧縮空気を案内するフロートと、
前記ピストン部材の内部に前記圧力室に位置させて装着され、前記ピストン部材に対して前記開閉部が前記排水孔を開く方向に付勢する常開ばねと、
前記ピストン部材の外方に突出して設けられたばね受け部材と前記受け台との間であって前記ピストン部材と前記支持筒体との間に形成された常閉ばね収容部内に装着され、前記常開ばねの付勢力よりも大きな付勢力を前記開閉部に対して前記排水孔を閉じる方向に付勢する常閉ばねとを有し、
前記常開ばねと前記常閉ばねとにより前記開閉部に対して前記排水孔を閉じる方向に付勢する常閉形から、前記常閉ばねを前記常閉ばね収容部から取り外して前記フロート室内に圧縮空気が供給されないときに前記開閉部が前記排水孔を開く常開形に切り換え得ることを特徴とする常閉形フロート式オートドレン。
