本文以實驗方法鑑別圓桿節流器之節流參數及彈簧順從係數，探討節流器補償靜壓軸承工作壓力的特性，實驗使用平面靜壓軸承工作台，經由測量節流器進口壓力、出口壓力及流量，使用最小誤差平方偏導數方程式聯立求解，得到滑桿節流常數、位移係數。實驗測試四個圓桿節流器，以三種供油壓力測試出此圓桿節流器量測數據，將帶入圓桿式節流器連續流量方程式，使用最小誤差平方法，分析滑桿節流常數、位移係數，在供油壓下通過鑑別流量，圓桿式節流器對負荷變化造成彈簧對壓力流量的調節，鑑別出最佳化設計。

In this paper, the experimental method of identifying the throttle throttle rod spring obedience coefficient parameters and discuss the work of the throttle pressure compensated hydrostatic bearing characteristics, experiments using hydrostatic bearing flat bench, by measuring throttle inlet pressure, outlet pressure and flow, using least square error partial derivative equations solved simultaneously to obtain a constant throttle slider displacement factor.
Experimental test four restrictor rod, oil pressure test in four out of this circle have measured the throttle lever Data, into a round rod continuous flow restrictor equation, using the minimum error square method to analyze slip Constant throttle lever, the displacement factor, the oil differential pressure flow through a round rod throttle pressure caused by spring flow regulator to load changes, identify the optimal design.
