Description
図1は、10ベーン形・標準ポンプのカム面輪郭を示す図であり、
図2は、本発明に基づく10ベーン形・ポンプのカム面輪郭を示す図であり、
図3は、本発明に基づく12ベーン形・ポンプのカム面輪郭を示す図であり、
図4は、本発明に基づく12ベーン形・ポンプのカム面輪郭のカム面経過を回転角度に関連して示す図であり、
図5は、本発明に基づく12ベーン形・ポンプのカム面輪郭に沿ったベーン行程の特性を回転角度に関連して示す特性線図であり、
図6は、本発明に基づく12ベーン形・ポンプのカム面輪郭に沿ったベーン容積内の圧力変化の特性を回転角度に関連して示す特性線図である。
(角度に依存した半径変化の関数)の転換点を有していて、最終的に69°、即ち角度位置9で終わっている。カム曲線区分の転換点の位置は、回転角度に依存したカム曲線区分の最大値と最小値とによって(正確に)規定される。角度位置9から、即ち69°から角度位置11まで、即ち111°までいわゆる大径円弧区分を延在させてあり、該大径円弧区分は、回転角度に依存してベーン行程の半径方向内側へのわずかな減少に基づき、ベーン頭部を常に輪郭(カム面)に圧着させるようになっている。大径円弧区分はさらに、次のように規定されていてよく、即ち大径円弧区分の始端がカム曲線区分の最大値を形成し、終端がカム面輪郭の第1及び/又は第2のカム面区分でもはや接線成分を生ぜしめないようになっていてよい。角度位置11、即ち111°から本来の下降区分を延在させてあり、下降区分は165°まで、即ち角度位置15まで延びていて、ベーンポンプの吐出区分を形成しており、それというのは行程容積は減少されるからである。下降区分は角度位置13に、即ち135°に同じくカム面区分の転換点を有している。角度位置7、即ち上昇区分の転換点と角度位置13、即ち下降区分の転換点とはほぼ90°にわたって互いに離間されている。10ベーン形・ポンプは36°の角度ピッチ(ベーン位置間角度)を有しているので、前記離間は角度ピッチの2.5倍に相当する。即ち、1つの上昇区分の転換点と次の上昇区分の転換点とも、角度ピッチの2.5倍にわたって互いに離間されている。さらに転換点の位置は、カム面輪郭の主軸線に対して対称である。165°、即ち角度位置15から180°まで、即ち角度位置17まで、次の小径円弧区分の半分が延びている。180°から360°まで、即ち角度位置17から始めの角度位置3まで、カム面輪郭は前述のカム面輪郭半部に対して対称的に繰り返される。
