Abstract
The present disclosure shows a hydraulic regeneration circuit for a hydraulic cylinder that enables multiple extension speeds for the cylinder even while using fixed displacement pumps. The regeneration circuit uses the expelled fluid to drive a hydraulic pump/motor combination to create 4 or more speeds, as opposed to the 2 speeds typical in regeneration circuits. By using directional flow control valves, the fluid can be combined in such a way that the operator can choose a speed multiplier for the hydraulic cylinder to operate at.
