Abstract
Viene descritto un dispositivo di alimentazione dell'aria o di una miscela di aria e di combustibile per un motore a combustione interna del tipo costituito da un condotto dell'aria (2) o della miscela di alimentazione, la cui sezione di passaggio è controllata da una valvola a farfalla (3) azionata da un pedale dell'acceleratore attraverso una trasmissione e provvista di una lamina otturatrice, supportata da un albero (4), oscillante attorno ad un asse ortogonale all'asse longitudinale del condotto a valle della valvola a farfalla agendo una depressione generata dal motore; l'asse dell'albero è posizionato rispetto a detto condotto ad uno prefissata distanza "e" dall'asse longitudinale del condotto, in modo che a detto albero oscillante venga applicata dalle pressioni dell'aria che agiscono sulle superfici di detta lamina otturatrice, una coppia tendente a portare detta lamina oscillante nella posizione di chiusura.(Figura 1).An air supply device or a mixture of air and fuel for an internal combustion engine of the type consisting of an air duct (2) or of the supply mixture, the passage section of which is controlled by a butterfly valve (3) operated by an accelerator pedal through a transmission and equipped with a shutter plate, supported by a shaft (4), oscillating around an axis orthogonal to the longitudinal axis of the duct downstream of the butterfly valve acting a depression generated by the engine; the shaft axis is positioned with respect to said duct at a predetermined distance "e" from the longitudinal axis of the duct, so that air pressure acting on the surfaces of said shutter plate is applied to said oscillating shaft, a pair tending to bring said oscillating plate into the closed position (Figure 1).
