A lubricating arrangement with flow control and distribution priority, through the analysis to the lubricated bad problem of present breaker, have the not enough of flow distribution function to centralized oil supply, the lubricated scheme central plain of dispersion, provided to reform transform the scheme of renewal to lubricating arrangement, design the lubricated adjusting device of neotype flow control of having and distribution priority. It is preferential lubricated to guarantee not only that above -mentioned B branch road obtains, and A, two branch roads of B all can obtain equitableflow distribution in addition, reach the mesh of sufficient lubrication for the whole moving stability of breaker, reliability, economic nature all improve a lot.
