Abstract

The carburettor has two air intakes (1, 2). The throttle (5) of the first is controlled directly by the accelerator pedal (6). The throttle (9) of the second is controlled by a lever (10) moved against a spring (16) by the membrane (13) of a bellows (12). One side (15) of the bellows is open to atmosphere and the other side (14) is connected through a solenoid valve (19) to the throats (3, 7) of the air intakes (1, 2). The second throttle is thus made to follow the movement of the first. A switch (29) de-energises the solenoid, closes the connection to the bellows chamber (14) and thus allows the spring to keep the second throttle permanently shut. A mechanical instead of pneumatic mechanism is also possible.
