  • Spiral air induction
    Patent number: 7648331
    Abstract: The nozzles are in the form of blowing-in openings in the housing wall which bounds the flow channel. The blowing-in openings are fed directly by means of air which is extracted from the flow channel downstream from the diffusor. This air is at a higher pressure than the flow in the flow channel upstream of the diffusor. This results in a passive, dynamic stabilization system for a compressor stage in the high pressure-ratio range, which does not require any additional control or actuating elements.
    Type: Grant
    Filed: October 2, 2007
    Date of Patent: January 19, 2010
    Assignee: ABB Turbo Systems AG
    Inventors: Zoltan Spakovszky, Christian Roduner
