Abstract
PURPOSE: To perform good starting without using another starting unit, by providing the plunger of a fuel injection pump with two communication passages to control the quantity of injection and by using a control ring to shut off one of the communication passages at the time of starting.
CONSTITUTION: A plunger 7, which is reciprocated and swung by the action of a cam 8, is provided in a pump casing 3. Fuel pressurized by the plunger 7 is supplied to an injection nozzle, which is not shown in the figure, through the longitudinal hole 12 of the plunger and the passage hole 15 of the casing 3. The plunger 7 has two communication passages 17, 20, through which the longitudinal hole 12 and a fuel chamber 4 in the casing 3 are connected to each other. The quantity of the fuel through the communication hole 17 is regulated by the action of an ordinary spill ring 16. A control ring 21, which shuts off the other communication hole 20 only at the time of starting, is provided in the communication hole so that the hole can be opened and closed. Therefore, the supplied quantity of the fuel to the nozzle can be increased and decreased.
