Embodiment Construction

[0028] figure 1 A fuel filter unit according to the invention is shown with a fluid line 1 , here a pump connection 8 can be seen in the figure. figure 1 The side of the fuel filter unit facing the bottom of the swirl pot in the inserted state of the swirl pot is shown. Proceeding from the substantially cylindrical pump connection 8 , the circular base 12 of the pump connection 8 and the damping region 2 can thus be seen. Connected to the fluid line 1 is a pump prefilter 3 which is designed essentially as a flat rectangular parallelepiped. A flat rectangular parallelepiped is here understood to be a rectangular parallelepiped in which two surfaces parallel to one another have a significantly larger area than the other sides of the rectangular parallelepiped. In the example shown, the prefilter 3 is stretched on the filter carrier 4 . The fuel filter unit shown also has a fastening part 5 with which it can be installed in a swirl box.

Abstract

A fluid line for transporting fuel from a pump pre-filter to a fuel pump, which damps the noises of the fuel pump and a fuel delivery unit that is equipped with said fluid line Damping is achieved by at least one damping region, which is situated opposite the intake opening and which damps vibrations originating from the fuel pump.

Description

technical field [0001] The present invention relates to an acoustically optimized fluid conduit for fluid transfer between a pump and a pump prefilter. The invention also relates to a fuel filter unit and a fuel pump unit with acoustically optimized fluid lines. Background technique [0002] A fuel transfer unit for transferring fuel from the fuel tank to the engine is usually installed in the fuel tank of the motor vehicle. The important components of this fuel delivery unit are: the fuel pump; the pump pre-filter; and the swirl box in which the fuel pump is placed so that it state, the pump will not run without lubrication. [0003] The pre-filter is connected before the fuel pump. The pre-filter filters the fuel before it is drawn from the pump to the engine. Such a pump prefilter can be arranged in the bottom of the swirl box, so that the pump draws fuel through the prefilter in the bottom of the swirl box. However, a problem with this arrangement is that only the b...
