Abstract
A hydraulic flow divider has first and second flow control valves each dividing its inflow into two flows. The first flow control has a pressure relief valve and a constant orifice dividing flow to two outlets. The second flow control further divides one of these flows into a second set of two output flows. One of the output flows of the second flow control valve is directed to a power steering cylinder while secondary output flow of the second flow control valve joins flow from the other outlet of the first flow control. The arrangement secures adequate fluid supply to a priority load of the hydraulic system at low pump drive engine speeds.
