摘要： A control system for a hydraulic pump in a hydraulic drive circuit includes at least one hydraulic pump whose displacement volume is variable, at least one hydraulic actuator driven by a hydraulic fluid delivered from the hydraulic pump, and a flow control valve connected between the hydraulic pump and the actuator for controlling a flow rate of the hydraulic fluid supplied to the actuator. In the control system, the target value of the differential pressure between the delivery pressure of the hydraulic pump and the load pressure of the actuator is preset, and the displacement volume is varied dependent on the deviation between the differential pressure and its target value for controlling a pump delivery rate so that the differential pressure is held at the target value. The control system further influences the change rate of the delivery pressure of the hydraulic pump with respect to the change in the displacement volume of the hydraulic pump, and determines a control gain (Ki) for the change rate of the displacement volume from the received value; and controls the displacement volume of the hydraulic pump in accordance with the control gain and the differential pressure deviation.

摘要： A load sensing control system for a hydraulic machine sets a variable target differential pressure between a delivery pump pressure and a load pressure of an actuator. A control factor is determined that becomes larger as the deviation between the target differential pressure and the actual differential pressure is increased, and that becomes smaller as the differential pressure deviation is decreased. The control factor also becomes larger as the target differential pressure becomes smaller. The target displacement volume for the hydraulic pump is based on the differential pressure deviation, which is calculated from the target differential pressure and the control factor.

摘要： A hydraulic system for a construction machine comprising plural hydraulic actuators (23-28) driven by fluid supplied from a pump (22), first and second flow control valves (29-34) for controlling flows of fluid supplied to the first and second actuators, and first and second distribution compensating valves (35-40) for controlling first differential pressure (.DELTA.P v1-.DELTA.P v6) produced between inlets and outlets of the first and second flow control valves. The first and second distribution compensating valves have respective drives (45-50, 35c-40c) for applying control forces (Fc1-Fc2) in accordance with the second differential pressure to the associated distribution compensating valves, to thereby set target values of the first differential pressures. The hydraulic system includes first means (59) for detecting the second differential pressure (.DELTA.P LS) from the discharge pressure (P s) of the pump (22) and the maximum load pressure (P amax) out of the first and second actuators; second means (61) for calculating individual values (Fc1-Fc6), as values of the control forces applied from the drives (45-50, 35C-40C) of the first and second distribution compensating valves (35-40), in accordance with at least the second differential pressure detected by the first means; and first and second control pressure generators (62a-62f) provided in association with the first and second distribution compensating valves. The first and second control pressure generators (62a-62f) produce control pressures (P c1-P c6) dependent on the individual values obtained by the second means and output the control pressures to the drives (35c-40c) of the first and second distribution compensating valves.

摘要： Described herein is a variable displacement bent axis type hydraulic machine having a center shaft within a casing in a tilted state along with a valve plate and a cylinder block, and provided with a tilt angle sensor mechanism for detecting the tilt angle of the valve plate. For the purpose of improving the resolution in angle detection, the tilt angle sensor mechanism is constituted by a support shaft rotatably supported on a side wall of the casing at a position deviated toward the valve plate from the pivoting point of the center shaft, a rocking lever having one end thereof securely fixed to the support shaft and the other end pivotally supported at one side of the valve plate, and an angle sensor adapted to detect the rotational angle of the support shaft resulting from rocking movement of the rocking lever. This arrangement permits a wider rotational angle for the support shaft to guarantee higher resolution in the tilt angle detection.

摘要： The displacement of a variable displacement hydraulic pump (1) which is driven by a diesel engine (27) is so controlled as to be set to a first target displacement to keep a pump pressure higher than a load pressure by a predetermined target value, or a second target displacement to limit an input torque on the basis of the pump pressure. Provided is a stand-by flow rate control portion (65) which outputs a third target displacement larger than the minimum value of said first target displacement. The displacement of the pump (1) is controlled so as to be set to the third target displacement when the third target displacement is output from the stand-by flow rate control portion (65).
