Hydraulic System Recovering Swing Kinetic and Boom Potential Energy
Swing kinetic and boom potential energy may be recovered in a machine having a movable work tool, a swing motor for rotating the work tool, a hydraulic cylinder for raising and lowering the work tool, a pump selectively connected to the swing motor and the hydraulic cylinder, and a power source outputting power to drive the pump. The machine may further include a first accumulator, a swing charge valve having a charge set pressure, and a boom charge valve. The swing charge valve selectively fluidly connect the swing motor to the first accumulator, and open to fluidly connect the swing motor to the first accumulator when a swing motor fluid pressure is greater than a charge set pressure of the swing charge valve. The boom charge valve may selectively fluidly connect a head-end chamber of the hydraulic cylinder to the first accumulator when the work tool is lowered.
