Carburator for internal combustion engines with electronic controlled organs capable of maintaining the idling speed of the engine at a constant level.

摘要

A carburetor comprising a main barrel (1) in which there is a throttle (5) which turns integrally with a shaft (6); an idle system (2) opens into the main barrel (1) through three holes (3a,3b,3c); a lever (7) splined to the shaft (6) and connected to the accelerator (8) to open the throttle (5) against the action of a spring (9); stop devices (10) operate on the lever (7) to define a first position of the throttle 5 for which the said holes (3a,3b,3c) are upstream; a second lever (11) is idle mounted on the shaft (6) and, by means of pushers (13) and against the action of a rod (17) positioned by a rotating cam (27) with an electromagnetic organ, rotates the first lever (7) and defines, when the accelerator (8) is released, small opening positions of the throttle (5) differing from the first position; a microprocessor gearbox processes the signals expressing the functioning conditions of the engine to operate the electromagnetic organ.
