Located on an air outlet (3) of an air inlet chamber leading to a mixture former is a star-shaped insert (6), which provides for evening-out of the air flowing out of the air outlet (3) by means of linearly oriented air conducting surfaces (8) arranged in a ray pattern. This results in more uniform mixture formation even at varying engine speeds.

Why it's free to use
- Filed December 20, 1989 and granted October 11, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 20, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
