Latest Patents
One of Ahn's latest patents is a hydraulic machine that features a pump to pressurize fluid using power from a power source. This machine includes an actuator that operates with the pressurized fluid, and a recovery part that captures energy from the fluid discharged from the actuator. The design allows for an operator to select between eco-mode and boost mode through a first operator input device. The recovery part consists of an accumulator that stores hydraulic energy and an assist unit that aids the power source using this stored energy. The controller ensures that the output power of the pump remains within specified limits depending on the selected mode.
Another patent by Ahn describes a hydraulic machine with a boom actuator that has both a large chamber and a small chamber. This design incorporates a recovery unit that captures energy from the fluid discharged from the large chamber. A recovery line connects the large chamber to the recovery unit, and an accumulator is linked to the recovery line. The system includes a discharge valve and a first sensor to measure pressure in the accumulator. The controller manages the discharge valve's operation to maintain the target pressure in the accumulator, ensuring efficient energy recovery.
