    摘要： A hydrostatic system is configured to be integrated in a vehicle, e.g. an excavator. The hydrostatic system may comprise a first closed hydraulic circuit including a first hydraulic pump and a first hydraulic motor configured to operate a first component of the vehicle, and a second closed hydraulic circuit including a second hydraulic pump and a second hydraulic motor rated to operate a second component of the vehicle. Furthermore, a single six-port two-position directional valve may be provided. The single six-port two-position directional valve may be configured to switch between a first position and a second position such that in the first position the first hydraulic motor is driven by the first hydraulic pump and the second hydraulic motor is driven by the second hydraulic pump, and in the second position the first hydraulic motor is disconnected from the first hydraulic pump and the second hydraulic motor is driven by both the first and second hydraulic pumps. The present disclosure also refers to a method for operating a hydrostatic system configured to be integrated in a vehicle.

    摘要： A hydrostatic transmission comprises a hydraulic pump, a hydraulic motor, first and second main fluid passages fluidly connecting the hydraulic pump to the hydraulic motor so as to constitute a closed fluid circuit, a charge fluid passage, a plurality of first charge check valves and a plurality of second charge check valves. The plurality of first charge cheek valves are interposed between the charge fluid passage and the first main fluid passage so as to allow only flow of fluid from the charge fluid passage to the first main fluid passage when the first main fluid passage is hydraulically depressed relative to the charge fluid passage. The plurality of second charge check valves are interposed between the charge fluid passage and the second main fluid passage so as to allow only flow of fluid from the charge fluid passage to the second main fluid passage when the second main fluid passage is hydraulically depressed relative to the charge fluid passage.

    摘要： A power beyond valve assembly for an agricultural implement includes a pressure compensation spool that receives hydraulic fluid from a hydraulic supply and selectively provides the hydraulic fluid to a hydraulic system of the agricultural implement. The position of the pressure compensation spool is adjustable between an open position that facilitates flow of the hydraulic fluid to the hydraulic system and a closed position that blocks flow of the hydraulic fluid to the hydraulic system. Additionally, two fluid connections provide the hydraulic fluid to either end of the pressure compensation spool to urge the pressure compensation spool to an open or a closed position. Further, a pressure relief valve is fluidly coupled to one of the fluid connections, and the pressure relief value is adjustable to vary hydraulic pressure within the hydraulic system.
