Zusammenfassung:A hydraulic circuit associated with a hydraulic actuator is provided having a reservoir situated to hold a supply of fluid and a pump situated to supply pressurized fluid to the hydraulic actuator. The hydraulic circuit also has a pressure intensifying valve fluidly connected to the reservoir and the hydraulic actuator. The pressure intensifying valve is situated to direct fluid to the reservoir while in a first position and direct fluid to the hydraulic actuator while in a second position. The hydraulic circuit further has a flow divider including a housing with an inlet fluidly connected to the pump, a first outlet fluidly connected to the hydraulic actuator, and a second outlet fluidly connected to the pressure intensifying valve. The flow divider also includes a first fluid transporting portion fluidly connected to the inlet and the first outlet and a second fluid transporting portion fluidly connected to the inlet and the second outlet. The flow divider further includes a first variable displacement actuator associated with the first fluid transporting portion. The first variable displacement actuator is situated to regulate a volume change associated with the first fluid transporting portion.
