- 円筒状の基部と、該基部の外周面から基部の軸線に直交する方向に延出する導出管と、該基部の外周面から該導出管の軸線上であって該導出管の延出方向とは逆方向に延出する第1導入管と、該基部と該導出管と該第1導入管との各軸線に直交する方向に延出する第2導入管と、基部内に液密かつ回動自在に設けられた円柱状体とを備え、該円柱状体に、その回動により該導出管と該第1導入管と該第2導入管とを選択的に連通させる切換路が形成された三方活栓において、
前記切換路は、前記導出管と前記第1導入管と前記第2導入管とが互いに全て連通している全通状態で、円柱状体をL字状に折れ曲がって貫通し、該第1導入管と該第2導入管とを連通させるL字状貫通孔と、該L字状貫通孔の該第2導入管と連通する側の一端から円柱状体の外周面に沿って該導出管側に延設され該導出管と連通する外周溝とによって構成され、前記導出管、第1導入管、第2導入管及びL字状貫通孔は同一平面上に存在することを特徴とする三方活栓。 - 請求項1記載の三方活栓において、
前記第2導入管の先端部には、通常時は閉塞し、前記第2導入管内に挿し込まれる接続具の挿入により開口される弁体を備え、
前記全通状態で、前記L字状貫通孔の前記第2導入管と連通する開口面が前記第2導入管の中心軸線に対して第1導入管側に偏心されていることを特徴とする三方活栓。 - 請求項1または請求項2に記載の三方活栓において、前記全通状態で、前記外周溝の前記L字状貫通孔の一端と連通する連通面は、前記L字状貫通孔の前記第1導入管と連通する他端の開口面を前記第1導入管の軸線方向に投影した投影領域の外方に位置することを特徴とする三方活栓。
