Embodiment Construction
[0044] figure 1 is a schematic illustration of a fuel injection system 10 comprising a fuel tank 12 and a feed pump 14 fitted with a low pressure regulator for delivering fuel via a low pressure fuel line or suction line 16 to an internally driven feed pump 18 . Fuel from feed pump 14 enters feed pump 18 through an inlet port or passage 20 where the fuel builds up pressure. High pressure fuel is discharged into an external manifold 22 for delivery to a plurality of fuel injectors 24 each fueled by a fuel injector manifold 26 . Alternatively, the pump 18 may directly supply oil to the branch pipe 26 (not shown in the figure).
[0045] The internally driven fuel supply pump 18 consists of a pump housing 28 and an inner chamber 30 into which low-pressure fuel is fed through the fuel supply passage 20 . An eccentric drive member 32 is rotatable within cavity 30 about drive shaft 34 to increase fuel pressure in the manner described below. A plurality of plunger cylinders 36 or ...
