Patent number: 11078962Abstract: A bearing assembly support comprises a body, the body defining: a thrust surface; an aperture extending through the body; and at least one passageway along which a lubricant can flow away from the thrust surface during use. The thrust surface is suitable for contacting an end of a bearing assembly. The aperture is suitable for receipt of a shaft when supported by the bearing assembly. Each passageway may be defined by a recess on the thrust surface or a cut away section that extends through the body from the thrust surface to an opposite surface of the body. The body may be a housing for receipt of a bearing assembly or an end cap for a housing.Type: GrantFiled: December 23, 2015Date of Patent: August 3, 2021Assignee: Cummins Ltd.Inventors: Philip Wild, Richard Goodyear, Christopher Normington

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
