Embodiment Construction

[0047] Identical or similar components are numbered with the same reference symbols in the figures. The figures show only embodiments and should not be interpreted as restrictive.

[0048] figure 1 A filter housing 110 according to an exemplary embodiment of the invention is shown in an isometric view. The filter housing 110 , preferably made of plastic, is provided as part of a filter system 100 for fuel filtration with an internal filter element and has a first housing part 112 in the form of a housing pot. and a second housing part 114 as a housing cover. The two housing parts 112 , 114 can be joined together at the outer edge 126 of the second housing part 114 and can be welded together at the connecting seam 130 , for example, in particular by ultrasonic welding. As an alternative, bonding of the two housing parts 112 , 114 is also conceivable.

[0049] Filter housing 110 has at least one inlet 102 and outlet 104 for fluid, in particular fuel. Outlet 104 is arranged ...

Abstract

The invention relates to a filter housing (110) for a filter system (100) for fuel filtering, comprising at least one inlet (102) and an outlet (104) for a fluid, wherein a circulating decoupling element (120) is provided on an outer periphery (116) of at least a first housing part (112), said decoupling element being electrically conductive. The invention further relates to a filter system (100)for fuel filtering, comprising such a filter housing (110).

Description

technical field [0001] The invention relates to a filter housing made of plastic for a filter system for filtering fuel, which filter housing is used in particular in an internal combustion engine of a motor vehicle, and to a filter housing with such a filter Housing filter system. Background technique [0002] A liquid filter housing is known from DE 10 2011 078 467 A1 in relation to cost savings in the manufacture of conductive plastic housings, which has a housing tank configured as a double-layer structure and the housing Tank latching housing lid. The housing pot and the housing cover together enclose an interior space. The inner layer of the housing pot facing only the interior is made of electrically conductive plastic, while the outer layer of the housing pot facing away from the interior is made of electrically insulating plastic, because The electrically conductive plastics are many times more expensive than non-conductive plastics. Due to the double-layer stru...
