Abstract
The present disclosure relates to filters in general, and the teachings may be applied to a filter assembly for use in a fuel injector, the fuel injector, and internal combustion engines. A filter assembly may include: a filter element with a frame having an axial end and a tubular filter housing receiving the filter element. The filter housing may have a side wall with a taper supporting the axial end. The taper may have the shape of a conic section with an opening angle γ of less than 180°. The outer circumferential surface of the frame may include a first section in the section of the taper having the shape of a conic section with an opening angle α of less than 180°.
