ABSTRACT:
A synchronizing cylinder that allows for the synchronized movement of multiple hydraulic mechanism cylinders having different sizes and volumes. In one embodiment, the synchronizing cylinder has a first chamber in fluid communication with a first mechanism cylinder and a second chamber in fluid communication with a second mechanism cylinder. The first mechanism cylinder has a first volume and the second mechanism cylinder has a second volume wherein the volume of the first mechanism cylinder is smaller than the volume of the second mechanism cylinder. The volume of the fluid being pushed from (or received by) the first chamber in the synchronizing cylinder is less than the volume of fluid being pushed from (or received by) the second chamber in the synchronizing cylinder so that the first and second mechanism cylinders extend and retract at the same speed and distance regardless of the smaller size and volume of the first mechanism cylinder.
