Patent number: 10612458Abstract: A variable geometry turbine comprising a turbine wheel mounted for rotation about a turbine axis within a housing. The housing defines an annular inlet surrounding the turbine wheel and defined between first and second inlet sidewalls. The turbine further comprises a cylindrical sleeve that is axially movable across the annular inlet to vary the size of a gas flow path through the inlet. The annular inlet is divided into at least two axially offset inlet passages. The inner diameter of the sleeve is greater than the inner diameter of the inlet passages.Type: GrantFiled: May 9, 2018Date of Patent: April 7, 2020Assignee: CUMMINS LTD.Inventors: John F. Parker, Robert L. Holroyd, Tom J. Roberts, James Alexander McEwen, Tim Denholm, Simon Moore, Michael Voong, Christopher Normington, Arun Vijayakumar, Stephen Garrett

Patent number: 9234525Abstract: A compressor wheel for a turbocharger comprising a central hub and a plurality of impeller blades extending outwardly from the hub. Each of the blades defines a leading edge, a trailing edge and a root portion which connects the blade to the hub. At least one of the blades has a surface provided with a variable thickness surface layer of a ceramic material. The leading edge of the blade is provided with a thicker surface layer of the ceramic material than the trailing edge of the blade, the root portion of the blade, or both the trailing edge and root portion of the blade.Type: GrantFiled: November 22, 2010Date of Patent: January 12, 2016Assignee: Cummins Turbo Technologies LimitedInventors: Michael Voong, Tom J. Roberts, Katie Rhodes, Luke Hankin
