Abstract

Un noto dispositivo con azionamento a motore elettrico e con meccanismo possiede cavi elettrici mobili e gli manca un potenziometro come rivelatore di posizione per il motore elettrico. La disposizione di questo potenziometro trova difficoltà costruttive.Queste difficoltà sono state risolte, nel nuovo dispositivo, per il fatto che il meccanismo è formato da una leva segmentale (19), oreintata dal motore elettrico (18), come una superficie di scorrimento a glifo (17) e una disposizione di leve articolate (10) costituita da una leva oscillante (9) collegata in modo fisso con l'albero (3) della farfalla e da una leva articolata (11) fissata in modo orientabile su questa, dove la leva articolata (11) poggia con due rulli di arresto (12,13) sotto la forza della molla (7), da un lato, contro la superficie di scorrimento a glifo (17) e, dall'altro lato, contro la superficie di arresto (14) di una leva di azionamento (15) regolabile a piacere e rispettivamente di una leva di regolazione (16) collegata con questa. Il nuovo dispositivo consente una regolazione/pilotaggio di riempimento del minimo senza ripercussioni sul pedale dell'acceleratore ecc.A known device with electric motor drive and mechanism has mobile electric cables and lacks a potentiometer as a position detector for the electric motor. The arrangement of this potentiometer finds constructive difficulties.These difficulties have been solved, in the new device, due to the fact that the mechanism is formed by a segmental lever (19), oreintato by the electric motor (18), like a sliding surface with a glyph (17) and an arrangement of articulated levers (10) consisting of an oscillating lever (9) fixedly connected with the shaft (3) of the butterfly and an articulated lever (11) fixed in an orientable manner on it, where the articulated lever (11) rests with two stop rollers (12,13) under the force of the spring (7), on one side, against the glyph sliding surface (17) and, on the other side, against the stop (14) of an actuation lever (15) freely adjustable and respectively of an adjustment lever (16) connected with it. The new device allows adjustment / piloting of the filling of the minimum without affecting the accelerator pedal etc.
