In regeneration, the cylinder will extend ___________.

In regeneration, the cylinder will extend ___________.

• A. At the same rate as retraction
• B. Slowly
• C. Quickly
• D. After a delay

Answer: (C)

Regeneration uses the fluid that would normally return from the rod end and redirects it to the cap end during extension. This adds the rod-end flow to the pump flow on the cap side, so more hydraulic fluid acts on the cap end in the same moment. Since extension speed is driven by the amount of flow into the cap end (flow divided by the piston area), having that extra flow makes the piston move faster. The result is a quicker extension, though this often comes with a change in the available force during that stroke. So, during regeneration the cylinder extends quickly.
