Abstract

The subject matter invention is an injection valve (10) for internal combustion engines, which essentially comprises a valve body (12); an input region (30) which exists in said body (12) and through which the fuel enters into the injection valve (10); a filter housing (32) which is provided inside said body (12) in order for the fuel to be cleaned at said input region (30); a filter (40, 50) which is connected into the filter housing (32), characterized by comprising a screwing surface (321) with a certain length on the internal surface of the filter housing (32); and an outer screw (41) with a certain length so as to correspond to the screwing surface (321) on the filter (40, 50).
