往复组合阀自动换向机构的设计研究

ON DESIGN RESEARCH OF AUTOMATIC REVERSING MECHANISM OF RECIPROCAL COMBINATION VALVE

介绍了一种结构简单、紧凑的液控机构，采用缸、阀一体的结构形式，缸、阀之间通过液 控互相作用，实现高频的自动往复换向．这种液控机构可广泛应用于公路建设等行业，

In this article a hydaulic control mechanism with a simple and compact structure is introducecl. The high -fre- quency automatic reciprocal reversion is achieved in combination with cylinder and valve and throught their hydaulic control interaction. The hydraulic control mechanism can be widely applied to various kind of trades such as to highway construction and high efficiency reciprocal work in controlling the mechanism is achieved.
