In engineering hydraulic oil cylinder work in the, sometimes implementation components in short time stop work, not need engineering hydraulic oil cylinder passed energy, or implementation components in a paragraph work time within keep must of force, and movement speed very slow, even stop movement, in this situation Xia, not need hydraulic pump output oil liquid, or only need is small flow of hydraulic oil, so hydraulic pump output of pressure oil all or most from spill flow valve flow back tank, caused energy loss serious.
