    摘要： A first target engine speed is set in response to a command value commanded by a command unit. A second target engine speed equal to or lower than the first target engine speed is set based on the first target engine speed. When the first target engine speed is reduced, the second target engine speed is set to be constant or be decreased and a reduction range for decreasing the first target engine speed to the second target engine speed is set to be decreased. The reduction range is set at zero when the first target engine speed is equal to or lower than an engine speed at least at a maximum torque point.

    摘要： A hydraulic driving system includes a hydraulic cylinder with a cylinder tube and a cylinder rod, a main pump, a hydraulic-fluid path, a charge pump, a stroke position detecting unit, and a pump control unit. The hydraulic-fluid path forms a closed circuit between a main pump and the hydraulic cylinder. The cylinder rod expands or contracts depending on how hydraulic fluid is supplied and exhausted to and from first and second chambers. The charge pump replenishes hydraulic-fluid in the hydraulic-fluid path. The pump control unit performs flow-rate reduction control in which the pump control unit reduces a suction flow rate so that a suction flow rate of the main pump is equal to or less than a maximum discharge flow rate of the charge pump when the stroke position becomes closer to a stroke end of the cylinder rod than a prescribed reference position during the flow rate reduction control.

    摘要： An engine control device includes an engine-driven variable displacement hydraulic pump, a hydraulic actuator driven by oil from the pump, a control valve which controls the oil discharged from the pump, and supplies the oil to and from the hydraulic actuator, pump displacement detecting means, command means for selecting and commanding variable command values, and setting means for setting a first target engine speed in accordance with a command value, and a second target engine speed lower than the first target engine speed based on the first target engine speed. When the pump displacement increases and exceeds a first predetermined pump displacement when the engine is controlled based on the second target engine speed, a target engine speed is changed from the second target engine speed to a third target engine speed higher than the second target engine speed and equal to or lower than the first target engine speed.

    摘要： A target fan rotational speed (R.P.M.) corresponding to a temperature detected by a temperature detector is determined according to a set correlation and the capacity of a variable-capacity hydraulic pump is varied so that the rotational speed of a cooling fan becomes that determined target fan rotational speed. It thereby becomes possible to precisely control the blowing air volume (R.P.M.) of the cooling fan, and, when the cooling fan is driven with a hydraulic source, to construct a hydraulic circuit with fewer parts. Moreover, in cases where the torque absorbed by the fan-drive hydraulic motor fluctuates, control is effected to suppress fluctuations in the cooling fan rotational speed and stabilize the rotation. Furthermore, in cases where the load on the fan-drive hydraulic motor fluctuates, control is effected to suppress fluctuations in the cooling fan rotational speed and stabilize the rotation.
