Simplified Variable Geometry Turbocharger With Increased Flow Range
US Patent:
2013021, Aug 29, 2013
Filed:
Nov 3, 2011
Appl. No.:
13/881920
Inventors:
John P. Watson - Arden NC, US
David G. Grabowska - Asheville NC, US
David G. Grabowska - Asheville NC, US
Assignee:
BORGWARNER INC. - Auburn Hills MI
International Classification:
F04D 1/00
US Classification:
606051, 415205
Abstract:
A variable geometry turbocharger is simplified yet able to maintain pulse energy. In a first embodiment, a turbine housing is provided with a pivoting flow control valve which pivots about a point near the entry to the turbine housing. By moving the valve about the pivot point, the effective volume of the turbine housing volute is varied, thus effectively reducing the volume of exhaust gas in the volute, allowing control of exhaust gas flowing to the turbine wheel. In the second embodiment of the invention, a rotating wedge segment within the volute is rotated from a first position to a second position, changing the effective volume of the volute and allowing control of exhaust gas flowing to the turbine wheel.
