    • A pump assembly for a chilled beverage dispenser includes an axle oriented in a substantially vertical orientation at a predetermined location along a bottom wall surface of the dispenser bowl; an impeller which rotates about an axis defined by the axle; an inner pump shell that fits over the axle and defines an internal cavity for enclosing the impeller without impeding rotation of the impeller; and an outer pump shell that fits over and engages the lower pump shell, with a cavity being defined and maintained between the inner pump shell and the outer pump shell. As the bladed impeller rotates, beverage is drawn into the pump assembly along the bottom wall surface of the dispenser bowl, and is also discharged along the bottom wall surface of the dispenser bowl, thus providing maximum agitation of the beverage.
    • 用于冷冻饮料分配器的泵组件包括沿着分配器碗的底壁表面的预定位置处以基本垂直取向定向的轴; 围绕由轴限定的轴线旋转的叶轮; 内泵壳,其配合在所述轴上并且限定用于封闭所述叶轮的内腔,而不阻碍所述叶轮的旋转; 以及外泵外壳,其配合并接合下泵壳,空腔被限定并保持在内泵壳和外泵外壳之间。 当叶片叶轮旋转时,饮料沿着分配器碗的底壁表面被吸入泵组件中,并且也沿着分配器碗的底壁表面排出,从而提供饮料的最大搅动。
