Summary:The system comprises a component which requires vacuum, and which uses the suction pipe (1) of the engine as vacuum source. The component is connected to a venturi nozzle (2) which is arranged inside the suction pipe. The venturi nozzle is coaxially arranged in the suction pipe, and its flow cross-section (18) is only partially covered. The venturi nozzle, in the flow direction, is arranged after the throttle valve in the suction pipe. Die Erfindung betrifft ein Unterdrucksystem eines Kraftfahrzeuges mit einem Brennkraftmotor und einem Unterdruck benötigenden, das Saugrohr (1) des Motors als Unterdruckquelle nutzenden Bauteil. Das Bauteil ist an eine innerhalb des Saugrohrs angeordnete Venturi-Düse (2) angeschlossen.
