Abstract

Nelle valvole di iniezione note, con cui si ottiene una polverizzazione e una dosatura del carburante, si manifestano dispersioni di campionatura.La nuova valvola di iniezione è strutturata in modo tale che tra la valvola di dosatura e il dispositivo di polverizzazione sia disposto un sistema di misura di portata costituito da un cilindro di misura, da un pistone libero e da un sistema di rilevamento della corsa del pistone libero. In questo modo si è reso possibile mantenere esattamente la portata di carburante prefissata in modo nominale mediante rilevamento del valore reale della portata di iniezione che attraversa la valvola di iniezione.L'impiego della valvola di iniezione secondo l'invenzione assicura un funzionamento indisturbato, economico e privo di veleni di un motore a combustione interna, ad esempio in veicoli stradali.In the known injection valves, with which pulverization and metering of the fuel are obtained, sampling dispersions occur. The new injection valve is structured so that between the metering valve and the pulverizing device there is a system of flow measurement consisting of a measuring cylinder, a free piston and a free piston stroke detection system. In this way, it has been possible to maintain exactly the fuel flow rate set in nominal mode by detecting the real value of the injection flow rate through the injection valve. The use of the injection valve according to the invention ensures undisturbed, economic operation. and free of poisons from an internal combustion engine, for example in road vehicles.
