<p>The throttle has a aperture (9), and is fitted as an insert (5) into a fuel channel (2). A filter is positioned upstream of the aperture. A ring groove (10) is formed between channel wall (4) and insert upstream of the aperture. A wall of the insert upstream of the ring groove, and the channel wall form a ring gap (14), which acts as filter and is part of the connection between the sides of the insert. The section of the ring gap is larger than that of the aperture.</p> |
