Definitions
- the single figure shows a schematic representation of the interaction of the essential components of a fuel injection system according to the invention.
- a pre-pressure pump 1 is from a tank 2 fuel via a filter device in a
- the amount of fuel to be supplied to the pump working chamber 9 is arbitrarily adjustable, for example, as a function of a pressure in a high-pressure accumulator.
- the fuel introduced into the pump working chamber is conveyed via a high-pressure line 11 into the high-pressure accumulator. A necessary for this promotion
