Problems solved by technology

[0004] The piping connection of the pressure limiting valve 13 and the flushing valve 14 to the pressure accumulator unit 9 via the high pressure lines 15 , 16 is disadvantageous because additional sealing points are created due to this
In addition, the piping connection of the above-mentioned components of the fuel supply system results in a structurally complex fuel supply system requiring a lot of installation space
Access to individual components of the fuel supply system is more difficult due to pipe connections

Embodiment Construction

[0042] The invention relates to a fuel supply system for an internal combustion engine, especially a common rail fuel supply system, especially designed as a large diesel engine or a marine diesel engine. The basic structure of this fuel supply system has been referred to figure 1 to describe.

[0043] The invention concerns the details of the fuel supply system by means of which, in the area of ​​the pressure accumulator 9 interacting with the pressure limiting valve 13 and the flushing valve 14 , the plumbing work can be reduced. For details on this, refer to the following figure 2 to describe.

[0044] therefore, figure 2 Assignment of a valve block 19 to the pressure accumulator unit 9 interacting with the pressure limiting valve 13 and the flushing valve 14 is shown, wherein the pressure accumulator unit 9 acts directly on the valve block 19 , wherein the valve block 19 also accommodates or carries the pressure limiting valve 13 and flush valve 14.

Abstract

PROBLEM TO BE SOLVED: To provide a new fuel supply device for an internal combustion engine in which individual component of the fuel supply device has high improved accessibility, and provide a construction constituted by a storage unit, a pressure relief valve, and a cleaning valve of the fuel supply device.SOLUTION: A storage unit (9) in which the storage unit, a pressure relief valve, and a cleaning valve cooperate together is provided with a valve block. The valve block is directly mounted to the storage unit (9), and accommodates the pressure relief valve (13) and the cleaning valve (14).

Description

technical field [0001] The invention relates to a fuel supply system for an internal combustion engine. The invention also relates to the assembly of a pressure accumulator unit, a pressure limiting valve and a flushing valve of such a fuel supply system. Background technique [0002] figure 1 The basic configuration of a common rail fuel supply system for an internal combustion engine known in the prior art is shown. Such a construction is known from DE 101 57 135 B4. therefore, figure 1 The common rail fuel supply system comprises at least one injector 1 each for each cylinder of the internal combustion engine. Fuel can be injected into the individual cylinders of the internal combustion engine via the injector 1 . The common rail fuel supply system also includes a pumping device 3 comprising at least one low-pressure pump 5, at least one high-pressure pump 2 and a high-pressure pump accumulator unit 8 to deliver fuel from the low-pressure zone 4 of the common-rail fu...
