摘要： 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.
