Orifice-Type Hydraulic Flow Divider

{0 Comments}

Theoretically, the orifice on both sides of the flow divider can be adjusted so that the ?P across the orifice plus the load ?P is equal on both sides. Then, the flow from the pump will divide equally, and both cylinders will extend at the same time. If the cylinders are the same size, they will extend at the same rate.

This solution works until the load ?P changes. Now, the flow goes to the lower-pressure side. The effect of some load fluctuation can be handled by a pressure-compensated flow control. Eventually, the cylinders get out of synchronization and have to be resynchronized.
