摘要
介绍一种改进型的电液比例方向阀。该阀简化了先导部件的结构,提高了阀的频响特性,其幅频宽可达12～15HZ。文中给出了其结构特点、工作原理和流量控制特性曲线。
This paper introduces an improved electro-hydraulic proportional direction valve. Being predigested its pilot unit, the valve has higher response frequency which reached to 12--15HZ. The construction characteristic, working principle and I-Q curve of the valve are given in this paper.
