Regeneration in hydraulic systems can only be achieved during what type of stroke?

Regeneration in hydraulic systems typically occurs during the advance stroke. This process involves redirecting the flow of hydraulic fluid to enhance efficiency and increase the speed of the actuator without the need for additional power input. During the advance stroke, the system can utilize the fluid that has been returned from the load to assist the movement of the actuator in the desired direction, effectively providing a boost in force or speed.

This regeneration capability is particularly useful in applications where rapid movement is required, as it allows for a faster cycle time and reduced energy consumption. The advance stroke is essential for applying this principle, as it is when the system is actively working to move the load.
