单通道液压开关及其应用

The Mono-port Hydraulic Switches and Their Application

通过对液压换向同的开关特性分析，提出了单通道液压开关这一新概念．这一种新概念指出，液压开关控制的实质是以单通道液压开关为基本元件的逻辑控制．并据此建立了各种换向阀的单通道液压开关模型．

Through the analysis of switching characteristic of Directional Control Valved,theadvanced conception of mono-port hydraulic switches is presented. This conception showsthat the substance of hydraulic switch control and electrohydraulic systems is the logicalcontrol of hydraulic actuators. According to this conception the mono-hydraullc switchmoulds of DCVs are established.
