    摘要： This document discloses an internal gear pump with a symmetrical casing and a head design that enables high pumping speeds, reduced turbulence and reduced risk or occurrence of cavitation. The head includes a boss that extends into the pump chamber to form an idler support and a crescent support. The crescent support includes a liquid directing step that extends from the crescent arcuately towards the inlet. The liquid directing step divides liquid incoming from the inlet into a portion directed to an idler feed slot and another portion directed to a rotor feed slot. The idler feed slot provides communication between the inlet and the roots of the idler and the rotor feed slot provides communication between the inlet and spaces between the rotor teeth.

    摘要翻译： 该文献公开了一种具有对称外壳和头部设计的内齿轮泵，其能够实现高泵送速度，减小的湍流并降低风险或气穴现象的发生。 头部包括延伸到泵室中的凸台以形成惰轮支架和月牙体支架。 月牙体支撑件包括液体引导步骤，所述液体引导步骤从月牙弓形地朝向入口延伸。 液体引导步骤将从入口进入的液体分成朝向惰轮进料槽的部分和引向转子进料槽的另一部分。 惰轮进给槽提供进口和惰轮根部之间的连通，并且转子进给槽提供进口与转子齿之间的空间之间的连通。
