摘　　要：以进油路节流调速回路为例,通过对进油路节流调速系统的特性进行分析,将溢流阀与节流阀的特性进行组合,确定了进油路节流调速系统的工作点;并通过组合特性曲线分析了负载F、节流阀通流面积a(x)、溢流阀初始压力p0、溢流阀特性变化对工作点的影响。Takes the meter in speed control system for example, determines the operating point of the meter in speed control system by analyzing the characters of the meter in speed control system and combining the character of the overflow value and the throttling value. It also analyses the effect of the load F, the throttling - flow area of the throttling value a （ x ）, the initial pressure of the overflow value P0 and the change of the over- flow value character for the operating point by the combined characters.

关 键 词：节流调速 进油路 工作点
