Abstract
The claimed invention is an end-of-stroke recirculation system for use with a hydraulic cylinder. Generally speaking, the fluid in a hydraulic cylinder remains trapped on one side of the piston and is unable to recirculate. The claimed invention provides a bypass that allows for hydraulic fluid to circulate through a cylinder when the hydraulic cylinder is at either end or both ends of its stroke.
