    • A regenerative toric pump in which undesirable noise generation and leakage through clearance gaps (26,36) between the impeller (46) and housing (20) is minimized includes an impeller (46) having vanes (58,60) lying in general planes radiating from the impeller axis (A) disposed at variable spacings from each other in a geometrically balanced pattern. Recesses (80,82,84) in one of opposed side surfaces on the impeller (46) and housing (20) are arranged in a pattern such as to minimize leakage through the clearance gap (26,36) between those surfaces from points in the pump chamber which are at different pressures.
    • 一种再生复曲面泵,其中不期望的噪声产生和通过叶轮(46)和壳体(20)之间的间隙(26,36)的泄漏最小化包括叶轮(46),叶片(46,60)位于辐射 从以几何平衡模式彼此以可变间隔设置的叶轮轴线(A)。 在叶轮(46)和壳体(20)的相对的侧表面中的一个中的凹部(80,82,84)被布置成图案,以使得通过这些表面之间的间隙(26,36)的泄漏最小化 泵室处于不同的压力。
