  • Patent number: 10968600
    Abstract: Disclosed embodiments are directed to distributed hydraulic systems, and power machines such as excavators including distributed hydraulic systems. In the distributed hydraulic systems, electronically controlled distributor blocks are located throughout the machine, particularly along the lift arm, to locally distribute hydraulic power to actuators of the various machine and implement functions. Distributing control of hydraulics in multiple locations reduces the number of hoses that must be routed from a main control valve to the various actuators on the machine.
