Abstract

Tali pompe vengono impiegate in connessione con motori elettrici come pompe per carburante per motori a combustione interna di autoveicoli.Quando sono sotto carico, dette pompe producono un rumore addizionale che può essere percepito in modo sgradevole.Al contrario, la nuova pompa presenta le caratteristiche che le parti rotanti della pompa sono strutturate in modo tale da ottenersi, per ogni settore di alimentazione, un diverso valore minimo e/o massimo del volume del settore oppure un diverso rendimento volumetrico.La nuova pompa è producibile con poca spesa e presenta una emissione di rumori notevolmente ridotta.These pumps are used in connection with electric motors such as fuel pumps for internal combustion engines of motor vehicles. When under load, these pumps produce an additional noise that can be perceived in an unpleasant way. On the contrary, the new pump has the characteristics that the rotating parts of the pump are structured in such a way as to obtain, for each supply sector, a different minimum and / or maximum value of the sector volume or a different volumetric efficiency. The new pump can be produced at low cost and has an emission of significantly reduced noise.
