A regeneration hydraulic circuit which increases the speed of one action of a double action cylinder. The hydraulic circuit includes first hydraulic line in fluid communication with one end of the double action cylinder, and a second hydraulic line in fluid communication with an opposing end of the double action cylinder. A third hyraulic line connects the first hydraulic line and the second hydraulic line. A pilot check valve is disposed in the third hydraulic line, and has a pilot line. The pilot line is connected to the first hydraulic line, wherein the pilot check valve is open when hydraulic fluid flows through the first hydraulic line and into the one end of the double action cylinder The pilot check valve is closed when hydraulic fluid flows out of the end of the double action cylinder and through the first hydraulic line. A check valve is disposed in the second hydraulic line, wherein hydraulic fluid flowing out of the opposing end of the double action cylinder is diverted into the third hydraulic line. |
