Abstract (en)
1. An automatic choke device for a carburettor, of the type comprising an arrangement for controlling a flap member (2a) and a throttle butterfly valve in a carburettor body (1a), said control arrangement essentially comprising rotary levers (8a, 9a) mounted on a shaft (7a), a heatsensitive element (5a) of bimetal strip type, a diaphragm unit (16a) controlled by the pressure obtaining in the intake duct, and a pull member (4a) which is pivoted at one end to a control lever (3a) which is fixed to the shaft (B) of the flap member (2a), characterised in that the first rotary lever (9a) of which one arm (18) is connected to the bimetal member (5a) is connected by way of a spring (11a) to a first arm (20) of the second rotary lever (8a) which is pivoted to the other end of the pull member (4a), the second arm (6a) of the second rotary lever (8a) being engaged with a traction rod (22a) of the diaphragm unit (16a), and that it comprises an adjustable abutment (17) positioned facing the arm (18) of the first rotary lever (9a) so as to limit the rotary movement of the latter in the direction of closure of the flap member (2a).
