  • Split valve pump controlled hydraulic system
    Patent number: 8783025
    Abstract: A hydraulic system that includes a controller controlling multiple hydraulic pumps to power multiple hydraulic functions. Any ratio of flow can be directed from each of the pumps to each of the functions, including having a pump dedicated to each function, or having one pump dedicated to one function and another pump supplying multiple functions including the one function. The controller can receive machine feedback and failure data indicating regions of the system with functional disruptions, and can direct flow from the pumps to the functions along routes that avoid the functional disruptions. The system can include operator input devices that provide operator inputs to the controller for controlling the system. The system can operate the hydraulic system in different modes, including modes to improve fuel efficiency and to improve productivity. The system can include a mode switch for operator selection of a desired mode.
