Description
軸方向に移動できるようになっているため、軸受はカムキャリヤの移動の際にカムキャリヤと同じ方向に移動でき、このことで、シリンダの隣接する2つのガス交換バルブ間の軸方向間隔が比較的短いにも関わらず、ガス交換バルブ間に配置された軸受の軸受幅を大きくすることが可能になる。
軸受の軸方向移動はカムキャリヤの軸方向移動とともに行われる。そのために、軸受は発明の有利な形態によってカムキャリヤの対向する2つの境界面間のレセスに挿入され、境界面の間隔は軸受の幅に一致し、カムキャリヤの移動の際に軸受をカムキャリヤとともに移動させるため境界面は軸受の反対側の端面に作用する。カムキャリヤの移動は、軸受から軸方向に離れた箇所に配置されたウオームギヤを使用して技術の現状に類似する方法で行われる。
2つの外側の移動位置、すなわち第1および第3の移動位置におけるカムキャリヤ3,4の軸方向移動経路はシリンダヘッドカバーの図示しないストッパーによってそれぞれ制限される。
