导向套内置换向阀全行程可调节油缸的设计

摘要

In view of actual needs, cylinder in job site is needed to adjust stroke length, and limitation that existing stroke ad-justable oil cylinder could not adjust travel in whole range should be overcome, through designing oil cylinder guide sleeve with built-in reversing valve and piston rod installed movable block,oil cylinder could obtain required travel in whole range of travel. So the prob-lem that oil cylinder stroke can be adjusted without disassembling oil cylinder is solved.%针对油缸在工作现场调整行程长度的需要,同时克服现有行程可调节油缸不能在全行程范围内调节行程的局限性,通过对油缸导向套内置换向阀、活塞杆外置可移动挡块的设计,油缸可在全行程范围内获得所需要的行程长度,解决了不需拆卸油缸就可调节油缸行程的难题.
