Abstract
Official abstract text for this publication.
A suction assembly for a centrifugal air filter, including an axial fan for generating a cooling air flow and a Venturi nozzle having a flow pipe and an intake port which opens out in a constriction region within the flow pipe. The flow pipe in the outflow direction of the axial fan is penetrated by the cooling air flow in such a manner that a vacuum is initiated in the intake port.
First claim
Opening claim text (preview).
The invention claimed is: 1. A suction assembly for a centrifugal air filter, comprising: an axial fan having one or more fan propellers which generates a cooling air flow through a heat exchanger disposed upstream of the axial fan; and a Venturi nozzle disposed in a peripheral region of the axial fan, the Venturi nozzle disposed downstream of the heat exchanger and the axial fan, and the Venturi nozzle having a flow pipe and an intake port which opens out in a constriction region within the flow pipe; wherein the flow pipe is at least partially disposed in front of and within the periphery of the one or more fan propellers in the outflow direction of the axial fan and is penetrated by the cooling air flow in such a manner that a vacuum is initiated in the intake port. 2. The suction assembly of claim 1 , wherein the Venturi nozzle is integrated in a fan casing that surrounds the axial fan. 3. The suction assembly of claim 2 , wherein the Venturi nozzle is an integral component part of the fan casing. 4. A commercial vehicle including an air filter system for cleaning a charge air flow of an internal combustion engine, comprising: a centrifugal air filter for the preliminary separation of coarse particles in the charge air flow; an axial fan having one or more fan propellers which generates a cooling air flow through a heat exchanger disposed upstream of the axial fan; and a Venturi nozzle disposed in a peripheral region of the axial fan, the Venturi nozzle disposed downstream of the heat exchanger and the axial fan, and the Venturi nozzle having a flow pipe and an intake port which opens out in a constriction region within the flow pipe; wherein the flow pipe is at least partially disposed in front of and within the periphery of the one or more fan propellers in the outflow direction of the axial fan and is penetrated by the cooling air flow in such a manner that a vacuum is initiated in the intake port. 5. The commercial vehicle of claim 4 , wherein the Venturi nozzle is integrated in a fan casing that surrounds the axial fan. 6. The commercial vehicle of claim 5 , wherein the Venturi nozzle is an integral component part of the fan casing.
