    • A tuner hose assembly for a motor vehicle power steering system including a flexible hose, a first flexible tuner tube inside the flexible hose having an upstream end connected to a pump, and a second flexible tuner tube inside the flexible hose having a downstream end connected to a power steering gear. A downstream end of the first flexible tuner tube is longitudinally separated from an upstream end of the second flexible tuner tube by a wave interference gap which terminates where an inner wall of the flexible hose is clamped against the upstream end of the second flexible tuner tube. The length of the second flexible tuner tube is selected, i.e. "tuned", to attenuate higher order pump fluid-borne noise and simulates a rigid metal tube of a prior tuner hose assembly having greater overall length.
    • 一种用于机动车辆动力转向系统的调谐器软管组件,其包括柔性软管,柔性软管内的第一柔性调谐器管,其具有连接到泵的上游端,以及柔性软管内的第二柔性调谐器管,其下游端连接到 动力转向装置。 第一柔性调谐器管的下游端通过波形干涉间隙与第二柔性调谐器管的上游端纵向分离,其中柔性软管的内壁被夹紧在第二柔性调谐器管的上游端。 选择第二柔性调谐器管的长度,即“调谐”,以衰减高阶泵流体噪声并模拟具有更大总长度的现有调谐器软管组件的刚性金属管。
