    Abstract: A fuel injection control device (an electronic governor (12) and a controller (13)) for an engine (1) is capable of controlling the governor region to an isochronus characteristic. A working machine controller (18) receives a delivery pressure signal (P) and controls a regulator (16) in such a manner that when the delivery pressure of a hydraulic pump exceeds a predetermined pressure (P1), the displacement volume of the hydraulic pump does not exceed a value determined by a preset pump absorption torque curve (20) and when the delivery pressure of the hydraulic pump (2) is not more than a predetermined pressure (P1), the displacement volume of the hydraulic pump increases as the delivery pressure of the hydraulic pump lowers from the predetermined pressure (p1). This makes it possible, even if the governor region is controlled to an isochronus characteristic, to increase the delivery rate of the hydraulic pump as the engine load becomes lighter.

    Abstract: When a mode signal Sm of a mode switch (13) is ON, an arithmetic unit (12a) of a controller (12) executes learning control in which a driving current (I) corresponding to a predetermined target pump rotation theta 0 is supplied to a proportional solenoid valve (3) to determine the difference between the target pump rotation theta 0 and actual pump rotation theta and the difference is stored as a corrective value DELTA theta 0 in an EEPROM of a memory unit (12b). When the mode signal Sm of the mode switch (13) is OFF, the arithmetic unit executes normal control in which the corrective value DELTA theta 0 stored in the memory unit (12b) is added to the target pump rotation theta 0 and a driving current (I) corresponding to this corrected target pump rotation theta 0 is supplied to the proportional solenoid valve (3). Therefore, even when any variance exists in the input/output characteristics of a regulator as displacement control means (control objet) of a hydraulic pump and the proportional solenoid valve, variance of actual pump rotation as the output of the control object can be reduced.

    Abstract: The invention is directed to a swashplate angle sensor (10) for a variable displacement hydraulic unit (1). The hydraulic unit (1) comprising a housing (2), within which a swashplate (3) with a rod shaped feedback-link (12) fixedly attached to the swashplate (3) is arranged pivotable around a swashplate axis (7). The angle sensor (10) comprising a magnet (16) mounted rotatable on a magnet carrier (13), and a sensor (15) for sensing the orientation of the magnet (16). The magnet carrier (13) is located in a control block (14) attached to the housing (2) and is located parallel to the feedback-link (12). The magnet carrier (13) is rotatable around a sensor axis (18) being parallel to the swashplate axis (7). A linkage spring (11) provides a connection between the feedback-link (12) and the magnet carrier (13) such that a pivoting of the swashplate (3) with the feedback-link (12) causes a rotation of the magnet carrier (13).
