Description
本発明において、一方向弁手段300は、図4及び図6に示すように、貫通孔121を取り囲んで弾力的に密閉させる円形断面の弾性バンド310と、キャップ200の内周面に形成され、キャップ200の軸方向移動により、弾性バンド310と接触して弾性バンド310を移動させる突起220と、弾性バンド310を、貫通孔121を密閉させる位置に復帰させる凹溝122とを備える。
本発明において、一方向弁手段300は、図7及び図8に示すように、貫通孔121を取り囲んで弾力的に密閉させる弾性バンド310と、キャップ200の内周面に形成され、キャップ200の軸方向移動により弾性バンド310と接触し、ハブ120の外周面と弾性バンド310の内周面との間に浮きを発生させる突起220とを備えることが好ましい。
第3の実施形態例は、上述した第2の実施例の変形例であって、弾性バンド310の外周面には、図9に示すように、突起220に対応する係止段311が突設される。
第4の実施形態例もまた、上述した第2の実施形態例を変形例であって、図10に示すように、突起220が、軸方向移動によりハブ120の外周面と弾性バンド310の内周面との間に挿入されるが、流通孔221が形成された楔形状である。
本発明において、一方向弁手段300は、図11に示すように、貫通孔121を選択的に開閉させる球320を有する周知の逆止弁である。
本発明において、一方向弁手段300は、図12に示すように、貫通孔121を選択的に開閉させる弾性フラップ330を有する周知の逆止弁である。
本発明において、一方向弁手段300は、図13に示すように、貫通孔121に連結される傾斜したスリット121aからなり、断面形状による独自の弾性変形により開閉される。
