摘　　要：开发了一种集液控单向阀、溢流阀和自调整背压阀于一体的背压自调整复合阀。使用背压自调整复合阀的液压缸系统,它的背压受工作压力反馈控制,即背压随工作压力变化而反向变化,起到改善液压缸系统对负载响应的性能和减振缓冲的目的。此外,该系统还具有锁位和溢流保护的功能。An automatic back pressure adjustment complex valve combining hydraulic control check valve, overflow valve and auto-adjusting back pressure valve has been developed. The back pressure of hydraulic cylinder system fitted with such a complex valve is controlled by the operation pressure feedback, that is the variation of back pressure varies reversely according to the operation pressure. The load response of hydraulic cylinder system and damping perfor mance are thus improved. On the other hand, the system possesses the function of locking and overflow protection.
