Abstract
Tali pompe vengono usate per autoveicoli con servo-dispositivi, dove ad ogni dispositivo è associato un recipiente e una camera di alimentazione con canale di ammissione.La nuova pompa per vuoto consente ciò per il fatto che è previsto almeno un altro canale di ammissione collegato con un altro recipiente o utenza e giunge a contatto con le camere di alimentazione giusto quando il primo canale di ammissione si è trasferito da questo nelle camere di alimentazione che si vengono a formare, dove il collegamento viene realizzato attraverso una fessura di comando della girante, che scopre l'altro canale di ammissione coperto da una superficie frontale della girante, in modo che più servo-dispositivi possono essere azionati con una pompa per vuoto ad azionamento semplice, dove si assicura che almeno un dispositivo non venga disturbato nel suo funzionamento dagli altri dispositivi.La nuova pompa per vuoto è adatta ad essere impiegata in autoveicoli.
