1.21 50/50 FLOW DIVIDER

TM 5-3895-373-34 1.21 50/50 FLOW DIVIDER. 50/50 flow dividers split the flow from a single input into two equal output flows. There are two types of 50/50 flow divider used in the paving machine. a. Gear-type flow dividers. Gear-type flow dividers are mounted on brackets that attach to the valve panel. There are three gear-type flow dividers in the paving machine. One flow divider splits the input flow to the two auger/conveyor systems. A second flow divider splits flow between the stack valve and the tow point cylinders. Each displaces 0.32 cubic inches (5,24 ml) per side. A third flow divider splits flow between two tow point cylinder circuits and has a displacement of 0.109 cubic inches (1,786 ml) per side. Hydraulic oil enters the inlet port and passes through two sets of meshing, double-gear assemblies. Each double gear assembly consists of two gears joined by a single shaft. As oil passes over the gears, they turn and engage an opposite set of gears. Hydraulic oil flow is equally regulated by the inertia created by the meshing sets of gears. Hydraulic oil output is equal from both outlet ports. b. Spool-type flow dividers. Spool-type flow dividers contain a pressure-compensated spool that balances oil flow. There is one spool-type flow divider located in the screed vibrator assembly. The flow divider input is channeled through a bored spool. The spool centers and self-adjusts as the oil passes through. This compensates for unequal hydraulic oil draw from each of the components and ensures an equal and constant output flow. 1-12
