An apparatus and method for cooling components associated with turbomachinery by means of one or more venturis placed in the intake flow of air into the compressor with an air inlet upstream of the venturis and an air outlet integral to at least one venturi. The partial vacuum created from the one or more venturis draws air past components that are desired to be cooled.


What is claimed is: 1. A method for cooling a component of a turbocharger, the method comprising the steps of: providing a turbocharger compressor with an ambient air intake flow; providing a cooling air inlet disposed in the ambient air intake flow to draw a portion of the ambient air and in fluidic connection with the component to be cooled, the component comprising a bearing system, a motor stator, or both; disposing a first venturi directly in the ambient air intake flow directly downstream of the air intake so that the first venturi receives a port...
