Abstract

Improved carburetor, which is of the type in which the diffuser section and the gasoline passage section are automatically regulated, increasing during acceleration and simultaneously with the opening of the throttle valve, while the throttle valve is activated. Gasoline, this valve is also actuated at the cold start when the starter is operated by controlling the opening of the throttle valve in the closing of its throttle valve, characterized by the automatic regulation of the diffuser section, which is achieved through of an articulated series of rods from the axis of the throttle valve until the free end of the last lever, articulated in a support fixed to the body of the carburetor, presses on the front end of a shaft integral with the movable part of the diffuser, complementary of a fixed and assisted by a recovery spring; the simultaneous variation of the section of gasoline passage in the needle valve, through the eccentric anchor of an angled lever, at the internal end of the throttle shaft, whose free end incorporates the initial pitch adjustment screw of gasoline, arranged axially, abutting the needle provided with recuperating spring and with a cylindrical guide extension in an axial hole thereof; acting simultaneously on a membrane valve for petrol supercharging during acceleration, when counting one of the articulated levers that controls the movement of the moving part of the diffuser, with an extension at the end of which articulates an oscillating lever through its central area at a point fixed of the body of the carburetor and whose free end presses on the diaphragm pusher of the valve assisted by a recovery spring; also controlling the performance of said gasoline turbocharging valve when the starter is operated, by means of a cam profile of the anchor handle of the starter cable, which strikes with another cam integral with the throttle shaft, displacing it angularly in the opening direction of the butterfly with the consequent increase in the section of the diffuser and gasoline passage.
