Title:

REGENERATIVE HYDRAULIC SYSTEMS AND METHODS OF USE

Document Type and Number:

WIPO Patent Application WO/2011/041410

Kind Code:

A3

Abstract:

Hydraulic systems (40) and methods for using such systems in a variety of machinery (100), including but not limited to machines having multiple functions performed by one or more hydraulic circuits. The systems (40) enable valves (50,52,54,56) and actuators (42,44) within the systems (40) to reconfigure themselves so that flow from assistive loads on one or more actuators (42,44) can be used to move one or more other actuators (42,44) subjected to a resistive load.
