Abstract
【解決手段】チャージ回路および補助回路の両方の圧力要求値を満たすことができる2つの独立的な出口を有するチャージポンプが提供される。チャージポンプは、少なくとも1つの入口と、互いに独立的な2つの出口とを有する多重ローラベーンポンプである。第1出口は、チャージ回路と流体連通し、第2出口は、補助回路と流体連通している。2つの出口は互いに独立しているため、ローラベーンポンプは、チャージ回路および補助回路の両方の圧力要求値を独立的に満たすことができる。2つの出口は、互いに直径方向に向き合っているのが好ましく、それにより、駆動軸にかかる負荷は減少する。ローラベーンポンプは、第1入口とは独立した第2入口を有しているのがよい。
