    Abstract: A hydraulic motor unit including a hydraulic motor (1′) which is connected to two working lines (3,4). The swiveling angle (α) of the hydraulic motor (1′) is adjustable by an adjusting unit (7) which is provided with a regulating piston (8) having two piston surfaces (9, 10). The regulation pressure acting on a first piston surface (10) in a regulation pressure chamber (12) can be adjusted by a control valve (13). The control valve (13) adjusting the regulation pressure is movable between two final positions. The pressure of a working line (3, 4) is applied to a first measuring surface (23) of the control valve (13) adjusting the regulation pressure while a second, opposite measuring surface (25) of the control valve (13) is impinged upon by a control pressure piston (34) at a force that depends on the control pressure only once a threshold value of a pipe (28, 18′) supplying control pressure has been exceeded.

    Abstract: A multi-piston pump is provided which uses microprocessor controlled checkall valves to control flow rate of a fluid at the pump's outlet port. The pump includes nine cylindrical shaped chambers and associated reciprocating pistons which are driven by a cam attached to a shaft. The pump's shaft is coupled to the shaft of a motor which, in turn, drives the pump's shaft and cam resulting in a fluid, such as seawater, filling each of the nine chambers and then having the fluid forced from the chamber by the movement of its associated piston from bottom dead center to top dead center. A pressure transducer which monitors the pressure at the pump's outlet port and a shaft encoder which monitors the angular position of the pump's shaft respectively provide analog signals indicative of the pump's outlet port's pressure and the shaft's angular position. A microprocessor receives these analog signals in a digital form, processes the signals and provides digital pulse signals to either extend or retract the rod of nine solenoids depending upon the pressure at the pump's outlet port. Each of the nine solenoid rods when extended engage a check ball valve within one of the pumps nine inlet passageways allowing the passageway to remain open when the associated reciprocating piston is in a pumping stroke. This allows seawater to be discharged through the inlet passageway maintaining fluid flow at the outlet port at a pressure level which is commensurate with the intended use of the pump.

    Abstract: A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The wobble plate is supported by a first fulcrum movable along the drive shaft around which it is disposed, at a diametrically central location, and by a second fulcrum at a location radially spaced from the drive shaft. The second fulcrum is formed by an end of an arm member disposed for rotation together with the drive shaft. The above end of the arm member is in camming engagement with a side surface of the wobble plate so that with an increase in the angularity of the wobble plate the second fulcrum moves toward the axis of the drive shaft through a substantial stroke, whereby the angularity of the wobble plate can vary at a reduced rate relative to a change in the pressure in the crankcase, thereby enhancing the stability of capacity control.

    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.
