Differential Circuit

When the cylinder is pushed forward, working fluid discharged from the cylinder head is added back to the cylinder cap because of the difference in surface area between the cap and the head of the cylinder. This achieves a faster-cylinder-forward motion, compared to a circuit with only one channel of incoming flow.

The relationship between forward speed V and the rod area, and between output force F and the rod area, are obtained as follows. V and F are functions of the rod area. The size of load pressure and pressure loss require due attention.
