    Abstract: An fuel injection control unit (an electronic governor 12 and a controller 13) for an engine 1 is capable of performing control in a governor region based on an isochronous characteristic. A working machine controller 18 receives a delivery pressure signal P and controls a regulator 16 such that, when the delivery pressure of a hydraulic pump exceeds a predetermined pressure P1, the displacement of the hydraulic pump does not exceed a value decided in accordance with a preset pump absorption torque curve 20. Also, the working machine controller 18 controls the regulator 16 such that, when the delivery pressure of the hydraulic pump 2 is not higher than the predetermined pressure P1, the displacement of the hydraulic pump is increased as the delivery pressure of the hydraulic pump lowers from the predetermined pressure P1. As a result, even when the governor region is controlled based on the isochronous characteristic, the delivery flow rate of the hydraulic pump is increased as an engine load reduces.

    Abstract: A pump or compressor wherein the volumetric displacement of a piston cylinder assembly is variable. The piston is connected to a crank slider or eccentric mechanical drive, the crankshaft of which oscillates alternately clockwise through a controllably variable angle .theta. and counterclockwise through substantially the same angle .theta., the angle .theta. being measured from the angular position of the crankshaft or eccentric at which separation between piston and the closed end of the bore is a minimum (Top Dead Center). The angle of crank oscillation controls the degree of volumetric displacement of the piston. The crank shaft is connected to a torsional spring so as to substantially resonate the rotational inertia of the moving parts. An oscillating electric motor supplies the oscillating torque to drive the mechanism at constant frequency but controllably variable angular amplitude.
