摘要: A hydraulic system is provided having a reservoir configured to hold a supply of fluid. The hydraulic system also has a variable displacement pump configured to supply charge fluid and pilot control fluid to the hydraulic system. In addition, the hydraulic system has a closed-loop portion configured to receive charge fluid from the variable displacement pump and drive a mechanism. The hydraulic system further has a pilot fluid supply portion configured to direct pilot control fluid from the variable displacement pump to closed-loop portion.
