<p>The carburettor has a ventilation channel which is connected by one of its apertures to the mixing chamber. It is connected by the other aperture (9) to the air input tube (8), so that the air going to the mixing chamber has to pass through the air filter. The ventilation channel may be divided into a first rising sector (1') and a second sector (7) perpendicular to the first sector and running axially to the inlet tube in the main body (2) of the carburettor. The aperture opposite the mixing chamber connects to the end neck (10) of the main body on which the air filter is mounted.</p> |
