End of Stroke Synchronization in Rotary Geared Flow Divider

Accuracy of division of flow using any type of flow divider has its own limitations due to clearance in the moving components. In case of Rotary geared Flow divider, the clearance between gears and the body causes internal leakages leading to inaccuracy in flow diversion. Accumulation of these inaccuracies is undesirable in the products it is used for. Accumulation of error caused by inaccurate flow division may cause machine breakdown.
It is therefore essential to eliminate the possibility of accumulation of such errors. The method used to eliminate accumulation of errors, is shown in the circuit below.
The CircuitNote: The circuit assumes that there are positive load bearing stops placed at each end stroke of each cylinder.
