摘要： A valve is provided for a hydraulic system having a source of pressurized fluid, a fluid actuator, and a proportional pressure compensating valve. The valve has a bore in fluid communication with the source and the fluid actuator. The valve also has a valve element disposed in the bore and movable between a flow blocking position and a flow passing position to selectively fluidly communicate the source with the fluid actuator. The valve also has a valve signal passageway disposed within the valve element and configured to be in fluid communication with a pressurized fluid having a signal pressure indicative of pressure supplied to the fluid actuator. The valve further has first and second orifices disposed within the valve element in fluid communication with the valve signal passageway and the bore. The valve signal passageway is configured to communicate the signal pressure with the first and second orifices. Movement of the valve element from the flow blocking position to the flow passing position fluidly communicates the first orifice with a system signal passageway before the second orifice, and fluidly communicates both the first and second orifices with the system signal passageway when the valve element is in the flow passing position.

摘要： A hydraulic system and earth-moving vehicle employing the hydraulic system are disclosed. The hydraulic system may include a first hydraulic cylinder and a second hydraulic cylinder, first and second hydraulic pumps and control valves to modulate provision of hydraulic fluid and pressure from the first and second hydraulic pumps to the first and second hydraulic cylinders as appropriate for the task being performed. If the task is digging with the earth moving vehicle, the first and second cylinders may be associated with tilting and lifting, respectively, and the control valves may be oriented so as to make each pump dedicated to one of the cylinders, and if demand is not being met, to then diminish power to the drivetrain to allow the tilting and lifting to be performed. The combiner may or may not be open during this time. If the task is not digging, a combiner valve can be opened to allow for cross-flow between the pumps and the cylinders.

摘要： A method for storing objects in an object storage system includes the steps of establishing a network connection with a client over an inter-network, receiving an upload request indicating an object to be uploaded by the client, selecting at least two storage nodes on which the object will be stored, receiving the object from the client via the network connection, and streaming the object to each of the selected storage nodes such that the object is stored on each of the selected storage nodes. The method can also include writing an object record associating the object and the selected storage nodes to a shard of an object database and generating a Universally Unique Identifier (UUID). The UUID indicates the shard and the object ID of the object record, such that the object record can be quickly retrieved. Object storage infrastructures are also disclosed.
