<p>A fluid mixing device in the form of a carburetor is described which has a system for metering fuel, The carburetor includes an air passageway (16, 18), and a throttle valve (14) which has a throttle aperture (26) and is movable across the air passageway (16, 18) to control the effective cross-sectional dimension of the throttle opening. The fuel metering system includes a fuel metering tube (40) extending through a complimentary lateral aperture (46) in the throttle valve such that the throttle valve (14) is slidable upon the metering tube (40). A longitudinal fuel distribution outlet extends (62) along one side of the fuel metering tube and the effective length of the distribution outlet (62) is controlled in dependence on the cross-sectional dimension of the throttle opening by the position of the throttle valve (14). The flow of fuel through the distribution outlet (62) is further controlled in relation to the pressure of air in the air passageway (16, 18), in a number of ways.</p> |
