Description
また、本発明は、より高精度化及び小型化が図れる往復動ポンプに適した逆止弁を提供することを他の目的とする。
また、このような吸入弁ユニット20及び吐出弁ユニット30にチャッキ弁を使用し、しかもバネ28が樹脂製であると、往復動による摺動抵抗によるチャッキ性の悪化や摩耗の問題が生じる可能性があるが、本実施形態に係るダイアフラムポンプによれば、バネ28の外周に突起29が形成されているので、摺動抵抗を削減することが出来る。
Claims (4)
- ポンプ室に臨む往復動部材の往復動によって吸入弁を介してポンプ室内に液体を導入し吐出弁を介して前記ポンプ室から液体を吐出する往復動ポンプであって、
前記吸入弁及び前記吐出弁は、液体の流通経路を有する本体部と、前記本体部の前記流通経路の入口側に設けられ、前記液体を通過させる孔が形成された弁座部と、前記本体部内に設けられ、前記弁座部の前記孔を開閉可能な弁体と、前記本体部内に設けられ、前記弁体を前記弁座部の前記孔に押し付けるバネとを備え、
前記バネの表面外周部には、前記本体部の内壁と接触可能な突起が前記本体部の内壁方向に向けて突出して形成されていることを特徴とする往復動ポンプ。 - 前記バネは、樹脂製であることを特徴とする請求項1記載の往復動ポンプ。
- 前記吸入弁及び前記吐出弁は、前記ポンプヘッドからポンプヘッドの中心軸方向に突出した状態で互いに並列して接続されていることを特徴とする請求項1又は2記載の往復動ポンプ。
- 液体の流通経路を有する本体部と、前記本体部の前記流通経路の入口側に設けられ、前記液体を通過させる孔が形成された弁座部と、前記本体部内に設けられ、前記弁座部の前記孔を開閉可能な弁体と、前記本体部内に設けられ、前記弁体を前記弁座部の前記孔に押し付けるバネとを備える逆止弁であって、
前記バネの表面外周部には、前記本体部の内壁と接触可能な突起が前記本体部の内壁方向に向けて突出して形成されていることを特徴とする逆止弁。
