摘要：<p>A filter holder (1) in an interior combustion engine is technically improved in comparison with the so far known holder and can be manufactured in an economical manner by pressure casting of aluminium or an appropriate aluminium alloy by means of simple and cheap casting tools or ingot moulds, and also with less subsequent mechanical working of castings at the same time. For this purpose, a pin (31) for the positioning of the air filter, protruding radially outwards from the wall (3) at a distance from a bottom (2), is designed in one piece with the holder's (1) casting and fitted with a striker face (311) which is shaped mechanically from the holder (1) casting's material, while at the same time, there is a pin (21) for the positioning of the fuel filter, arranged in the central area of the bottom (2), designed in a similar way in one piece with the holder's (1) casting and fitted with a striker face (211) - shaped mechanically from the holder (1) casting's material- by which a centrally arranged pass-through hole (212), executed directly into the holder (1) casting's material too, is surrounded. In addition, the opening (32) for the transition of pipes for the supply of air through the wall (3) is basically designed parabolically indeed - with its lower edge (320) at the transition between the bottom (2) and the wall (3) being flat and limited by points (321, 322) at both ends - but the parabolic section of the opening's (32) perimeter is concave and continuous with regard to the bottom (2) and executed so that it is to be found completely inside of the area between the lines which are running through the said end points (321, 322) of the straight edge (320) of the opening (32) in the direction (E) of moving together and moving apart of ingot mould parts prior to or after casting of the holder (1) respectively.</p>
