Zusammenfassung:The invention relates to a flow divider valve. The flow divider valve comprises a valve body, a valve rod located inside the valve body, a spring, a first transition block and an end cover installed at one end of the valve body, wherein the end cover is of a hollow structure. The first transition block is installed in the hollow structure of the end cover, and a cavity defined by the end cover, the valve body and the valve rod is divided by the first transition block into a pilot control containing cavity and a spring cavity internally provided with the spring, wherein the pilot control containing cavity and the spring cavity are independent; and an outer control signal is received through the pilot control containing cavity. An oil inlet and an oil outlet are formed in the valve body, a loading feedback opening is formed in the valve rod, and the pressure of the loading feedback opening enters the spring cavity. By means of the flow divider valve, independent control over the pilot control pressure and the loading feedback pressure can be achieved, the compensatory differential pressure of an automatic control flow divider valve is achieved through the change of the pilot control pressure, and then the consistency of the speed controlling performance of a hydraulic system with the flow divider valve at the different engine rotating speeds is guaranteed.
