Oil Hose Piping Structure of Automotive Power Steering System

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oil hose piping structure of a power steering apparatus for an automobile, and conventionally, when a steering wheel is rapidly rotated or a valve for opening and closing the oil passage is suddenly closed, And the return tube and the cooling tube have a very long length so that a large impedance is applied when the oil flows, thereby causing an oil hamming phenomenon and causing noise.;The present invention provides a separate reservoir between the return tube and the cooling tube, which can buffer sudden pressure fluctuations generated on the pipeline of the return tube for a first time, thereby suppressing noise generated by sudden pressure fluctuations.
