Beschreibung
Zusammenfassung:	The invention involves a vacuum generator apparatus with an electrically driven primary vacuum generator with a suction connection for sucking in a primary suction flow, and with at least one ejector apparatus, which has an inflow opening open to the environment, an outflow opening, and a suction opening that can be streamed through by a suction stream created at the suction opening from the inflow opening to the outflow opening, whereby the suction connection of the electrically driven primary vacuum generator is connected by flow with the outflow opening of the ejector apparatus.
