Abstract (en)
An adjusting fuel filter assembly for an injection valve comprises an external bush (42c) including a central longitudinal axis (L') and a circumferential step (42e) being arranged orthogonal to said axis (L'), said circumferential step (42e) segmenting the external bush (42c) into an upper section (42c') and into a lower section (42c"), whereby an outer diameter of the upper section (42c') is greater than an outer diameter of the lower section (42c"), and an internal filter material (42d), arranged within at least a part of said lower section (42c") and being of sintered material. The injection valve comprises a central longitudinal axis (L), a fuel inlet tube (15) with an inner surface, an actuator unit (6), and a valve assembly (4) including a valve needle (13). The injection valve further comprises said adjusting fuel filter assembly (42), whereby at least a part of the upper section (42c') of the external bush (42c) is either directly or indirectly engaged with said inner surface of the fuel inlet tube (15).
