- the further fuel filter can be designed with regard to the dimensioning and the required maintenance intervals for changing it independently of the other fuel filter in accordance with the lower requirements, since the fuel flowing back does not have as much contamination as the fuel drawn from the fuel tank.
- the volume of the further fuel filter can be designed with regard to the dimensioning and the required maintenance intervals for changing it independently of the other fuel filter in accordance with the lower requirements, since the fuel flowing back does not have as much contamination as the fuel drawn from the fuel tank.
- Fuel filters can also dampen pressure fluctuations and / or pressure surges in the return.
- the design according to claim 2 ensures that no fuel is conveyed into the return line by the feed pump.

- Fine filter is formed and through which the fuel delivered by the feed pump 10 flows.
- the fuel filter 20 is designed and dimensioned such that the fuel quantity delivered by the feed pump 10
- a maintenance interval for an exchange of the fuel filter 20 is defined in such a way that the function of the fuel filter 20 is ensured.
- the high-pressure pump 18 has, for example, a plurality of pump elements 19, each in one Have cylinder bore guided piston which is driven by a drive 17 in one stroke.
- the drive 17 can have, for example, a camshaft on which the pump pistons of the pump elements run, or 5 an eccentric shaft and a polygon moved through it, on which the pump pistons are supported.
- the high pressure pump 18 is preferably driven mechanically by the internal combustion engine.
- the fuel delivered by the high-pressure pump 18 becomes a reservoir 24 via a connection 23
- Each pump element 19 of the high-pressure pump 18 has an inlet valve 21, which opens into the pump element 19 and can get into the pump element 19 from the feed pump 10 through the fuel.
- Each pump element 19 also has an outlet valve 22 through which
- L5 fuel can be displaced from the pump element 19 to the reservoir 24.
- an injector 26 is provided, through which fuel is injected into the combustion chamber of the cylinder.
- Each injector 26 is connected to the connection 28
- a pressure transmission device 32 can be arranged in the connection 28 between the reservoir 24 and the injector 26, by means of which the pressure of the fuel supplied to the injector 26 is increased again compared to the pressure prevailing in the reservoir 24.
- a fuel metering device 34 is provided, through which the flow of fuel to the high-pressure pump 18 is set.
- the metering device 34 has an electrically operated control valve, which by
- an actuator 36 is switched, for example in the form of an electromagnet or a piezo actuator.
- the actuator 36 is controlled by an electronic control device 38.
- a pressure sensor 40 is arranged on the memory 24 and is connected to the control device 38.
- the actuator 36 is controlled by the control device 38 in such a way that the fuel metering device 34 adjusts a flow of fuel to the high-pressure pump 18, which is required in order to maintain a predetermined pressure in the reservoir 24 with the fuel delivered by the high-pressure pump 18.
- connection 48 leading to the drive 17 of the high-pressure pump 18 can be provided upstream of the fuel metering device 34.
- a pressure valve 50 which opens toward the drive 17, is preferably arranged in the connection 48, and the connection 48 only when a predetermined pressure is exceeded
- the pressure valve 52 ensures that, in particular when the internal combustion engine is started, if a high pressure is required in the accumulator 24 and this still has to be filled, the entire fuel quantity delivered by the feed pump 10 is supplied to the high-pressure pump 18
- a throttle point 52 is preferably provided downstream of the pressure valve 50, by means of which the flow in the connection 48 is limited. Downstream after the pressure valve 50 and the throttle point 52 can be from
- a return line 54 which opens upstream of the pressure valve 50 in the connection 16 and in which a throttle point 56 may be provided.
- the return line 54 can also open into the fuel reservoir 12.
- connection 48 is not to Drive area 17 of high-pressure pump 18 leads instead to a return line 80 into fuel reservoir 12.
- drive 17 of high-pressure pump 18 is lubricated in a different way, for example, by driving 17 with a lubricating oil circuit
- a return line 60 leads from the injectors 26 via a line via which fuel is not injected
- L5 is derived.
- the return 60 from the injectors 26 is not passed into the fuel tank 12 but opens into the connection 16 between the feed pump 10 and the high-pressure pump 18.
- the return 60 opens into the connection 16 upstream of the
- a further fuel filter 62 is arranged in the return 60 and downstream of this a check valve 64 which opens towards the outlet 60 in the connection 16.
- the check valve 64 has a spring
- SO reaches the return 60 as fuel delivered by the feed pump 10 in the return 60.
- a predetermined pressure in the return 60 can also be maintained by the check valve 64.
- Pressure relief valve 70 is arranged, which at Exceeding a predetermined pressure in the memory 24 opens and releases an outlet 72 from the memory 24, which opens into the return line 60 upstream of the further fuel filter 62. It can also be provided that an outlet 74 also discharges from the pressure booster 32, for example for fuel escaping as a result of a leak at the pressure booster 32 or a quantity of fuel required to control the pressure booster 32, the outlet 74 also flowing into the return 60 upstream from the another fuel filter 62 opens.
- the further fuel filter 62 in the return line 60 is designed as a fine filter, the fuel flowing through the return line 60 having only slight impurities from the high-pressure pump 18, the accumulator 24
- the additional fuel filter 62 in the return line can in particular also be suitably designed in accordance with the relatively high temperature of the returning fuel.
- the volume of the further fuel filter 62 in the return line can also dampen pressure fluctuations and pressure surges which are caused when the fuel injection at the injectors 26 is ended. In this way, an adverse influence on the setting of the flow to the high-pressure pump 18 by the metering device 34 is avoided.
- the further fuel filter 62 can also serve as a fuel cooler or a separate fuel cooler can be provided in the return 60 in order to lower the temperature of the returned fuel.
