- 高圧縮且つ長行程のピストン−シリンダー方式の内燃機関に用いるロータリー弁機構用の弁シールであって、ロータリー弁機構は二分割型シリンダーヘッド内に配置され、前記シリンダーヘッドは複数のロータリー吸気弁およびロータリー排気弁を受ける複数の胴体状収納キャビティを規定し、前記ロータリー吸気弁及びロータリー排気弁は球の2つの平行な面によって規定される球状断面を有し、前記平行面は前記球の中心の周りに対称の位置にあって球状周辺部及び平面端壁を規定し、前記ロータリー吸気弁及びロータリー排気弁は前記胴体収納キャビティ内の軸上に載置されてそれぞれが吸気口及び排気口に気密を保って接触しており、前記ロータリー吸気弁及びロータリー排気弁はそれぞれを貫通する燃料−空気の混合気の導入・中断用の流路及びシリンダーから排ガスを排出する流路を有し、前記吸気口及び排気口の前記ロータリー吸気弁及びロータリー排気弁それぞれの気密性は弁シール及び弁座によって保たれ、
前記弁シールは、断面が円形の弁シール本体を含んで構成され、該弁シール本体は前記吸気弁又は前記排気弁の球形外面に対応した環状に湾曲した上面を有し、該弁シール本体は前記吸気口又は排気口の開口部と合致する内環状壁により規定される貫通した開口を有し、該弁シール本体は潤滑用インサートリングを受容するように前記開口付近の前記湾曲した上面に形成された環状溝を有し、該潤滑用インサートリングは前記弁シール本体の湾曲した上面に相補する湾曲した上面を有し、
前記弁シール本体は更に外周壁を有し、前記弁シール本体の外周に複数の密閉リングの位置決め用に複数の環状リブが形成され、前記弁シール本体が前記弁座の外壁に気密を保って接触するように構成され、
前記弁座は、前記弁シール本体を受容するための環状溝を規定する外壁及び内壁を有し、前記弁座の該内壁は圧調整リングを受容するためその内面に形成された環状溝を有し、該圧調整リングは前記弁シール本体と接触し、該圧調整リングは、前記弁シール本体に上向きの気密を保つ圧力を及ぼすように、前記エンジンの圧縮及び出力行程中に圧縮ガスが通過する複数の開口部を有していることを特徴とする弁シール。 - 前記圧調整リングの平面図において前記開口部の形状は半円状を呈し、前記圧調整リングの外周上に形成されていることを特徴とする請求項1に記載の弁シール。
- 前記圧調整リングの通路の数により前記弁シール本体に及ぼされる所望の上向きの圧力が決まることを特徴とする請求項1に記載の弁シール。
- 前記弁座は前記二分割型シリンダーヘッドの溝に摩擦力により保持、位置決めされていることを特徴とする請求項1に記載の弁シール。
- 前記弁座は前記二分割型シリンダーヘッド内の環状溝にネジ止めされていることを特徴とする請求項1に記載の弁シール。
