IMPLEMENT POSITIONING HYDRAULIC CONTROL SYSTEM

摘要

A hydraulic control system is disclosed for selectively directing fluid to a pair of reciprocable jacks connectably disposed intermediate a frame and an implement such as a bulldozer blade for tilting and tipping the blade relative to the frame. The control system includes a fluid supply source, a flow divider valve which is in fluid communication with the supply source for providing equal flow to a pair of outlet paths, a first control valve arrangement for selectively communicating fluid from one of the outlet paths to either end of one of the jacks, and a second control valve arrangement for selectively communicating fluid from the other one of the outlet paths to either end of the other one of the jacks.
