摘要： In a hydraulic pump control apparatus and method of a construction machine, the control apparatus includes a pump control unit for controlling discharge pressure of a pump driven by an engine. The control unit includes: a pressure setting value calculating unit which calculates a pressure setting value based on an engine output torque estimating value or an engine RPM; and a breakdown treating unit selects one of the pressure setting value and a pressure command value according to a breakdown of the swash plate angle sensor to output the selected value. Since the pump is controlled according to a pressure setting value calculated based on the engine output torque estimating value, the absorption torque value of the pump does not exceed the maximum torque value of the engine even when the swash plate angle sensor breaks down, and related engine stoppage is prevented even during a high-load operation.

摘要： A pressure-regulating arrangement includes a main line through which a flow can pass from an intake to an output and in which an adjustable nozzle is arranged. The pressure-regulating arrangement further includes a pressure-regulating valve having a pressure connection which is connected to the main line downstream of the nozzle. A valve body of the pressure-regulating valve is movable from a basic position in an opening direction to increase an outlet pressure of an outlet connection. A first pressure which is tapped off from the main line upstream of the nozzle acts in the opening direction. The outlet pressure and a second pressure, which is tapped off from the main line downstream of the nozzle, act in a closing direction, which is opposed to the opening direction, in order to reduce the outlet pressure.

摘要： A pump control apparatus includes an actuator that varies a discharge capacity of a pump, and a regulator that regulates a control pressure led to the actuator. The regulator includes: a driving pressure port to which an average discharge pressure is led; a source pressure port to which a high pressure side discharge pressure is led; a signal pressure port to which a signal pressure is led; and a spool that regulates the control pressure using the high pressure side discharge pressure as a source pressure by moving upon reception of the average discharge pressure and the signal pressure. A driving pressure receiving surface that receives the average discharge pressure is formed inside the spool, and a signal pressure receiving surface that receives the signal pressure is formed in an outer peripheral step portion of the spool.
