    Abstract: A diesel engine fuel injection pump with electronic output regulation has an actuator cylinder for controlled displacement of a control rod which regulates a pumping element control screw. This actuator cylinder is machined in the pump body together with a seating for a distributor valve which controls the supply of hydraulic working fluid to the actuator cylinder. The working fluid may be the fuel itself.

    Abstract: A fuel pump for an internal combustion engine that transmits fuel with pressure by a lifting movement of a plunger that is caused to lift by a movement of a cam includes a lift amount changing mechanism. The lift amount changing mechanism includes a cam in which a height of a projection is varied along an axial direction of the camshaft, and a cam moving actuator that moves the cam along the axial direction of the camshaft. The lift amount of the plunger is changed by moving the cam along the axial direction of the camshaft. An amount of discharged fuel is controlled by changing the amount of discharged fuel per stroke of the plunger and is not determined only based upon the rotation speed of the engine. Therefore, the amount of discharged fuel can be increased with the engine rotated at a low speed, for example when the engine is being initially started, to improve a starting performance.

    Abstract: Apparatus and a method for effecting fuel viscosity/density compensation are disclosed. A combination of fuel flow through a viscosity sensitive annular orifice and a swirl-type orifice are utilized to create pressure differentials for driving a piston for regulating fuel flow. The components are positioned such that the direct variation of pressure drop across the annular flow orifice with viscosity change and the inverse variation of pressure drop across the swirl orifice with viscosity change, are combined to create an increased force for achieving the desired control effect.

    Abstract: An inertia governor mechanism applicable to a power unit providing a uniform preselected RPM when the power unit is subjected to variable loads. A pump means provides a constant supply of fluid at a constant pressure to a fluid circuit. A rotary disc valve in the circuit, having one or more axial openings therethrough and driven by the power unit to be regulated, varies the pressure of the fluid in the circuit inversely proportional to the speed, to provide a regulatory fluid pressure which acts on an expandable actuating cylinder to regulate the power unit with a constant speed.
