Latest Patents

One of Ooi's latest patents is an engine control device. This device sets a first target engine speed in response to a command value from a command unit. A second target engine speed, which is equal to or lower than the first, is established based on the first target engine speed. When the first target engine speed is reduced, the second target engine speed is either maintained or decreased, with a reduction range for decreasing the first target engine speed to the second target engine speed being minimized. This reduction range is set to zero when the first target engine speed is at or below the engine speed at the maximum torque point.

Another significant patent is a swing drive controlling system for construction machines. This system includes a variable displacement hydraulic pump that supplies pressure oil to a hydraulic actuator. It features a pressure detector that monitors the pump discharge pressure, a control valve for managing the supply of pressure oil, and a controller that adjusts the pump displacement. The system also incorporates a hydraulic motor for rotating the upper structure of the construction machine and a swing relief valve that defines the relief pressure of the hydraulic motor.
