Patent number: 12025016Abstract: A housing includes a seal, a first portion for receiving a first axial portion of a rotor, and a second portion for receiving a second axial portion of the rotor. The first portion includes a first cooling system having a cooling channel through which cooling medium flows and a first cooling channel intake, and a first abutment face which surrounds the first cooling channel intake. The second portion includes a second cooling system having a cooling channel through which cooling medium flows and a second cooling channel intake, and a second abutment face which surrounds the second cooling channel intake. The housing portions are connected so that the abutment faces rest on each other and the cooling channel intakes form a transition surrounded by the abutment faces. The seal is arranged between the abutment faces and extends around the transition and is spaced apart from the cooling channel intakes.Type: GrantFiled: May 10, 2023Date of Patent: July 2, 2024Assignee: BorgWarner Inc.Inventor: Wolfram Schaefer

Patent number: 11319964Abstract: A bearing housing for a turbocharger is presented. The bearing housing comprises a bearing housing body configured to receive a rotor shaft along a longitudinal axis of the bearing housing body. The bearing housing further comprises a hub connected to the bearing housing body and defining an opening into the bearing housing body, wherein the opening is configured to receive a rotor shaft bearing. Moreover, the bearing housing comprises at least one arm extending radially from the hub, the at least one arm having a first end connected to the hub and a second end opposite to the first end, wherein the second end of the at least one arm comprises a connection structure configured to connect the bearing housing with a compressor housing of the turbocharger.Type: GrantFiled: March 3, 2020Date of Patent: May 3, 2022Assignee: Borg Warner Inc.Inventors: Wolfram Schaefer, Grzegorz Rzepka

Patent number: 9695711Abstract: An exhaust-gas turbocharger (1) having a turbine housing (2), a compressor housing (3), a bearing housing (4) which has a bearing housing axis (L), and a connecting device (5) for connecting the bearing housing (4) to the turbine housing (2) and/or to the compressor housing (3). The connecting device has a multiplicity of screws (6), a number of screw holes (7, 7?) in the bearing housing (4) corresponding to the number of screws (6), and in the turbine housing (2) and/or in the compressor housing (3) a number of threaded holes (8) corresponding to the number of screws (6). The screw holes (7, 7?), the threaded holes (8) and the screws (6) are arranged at an acute angle (?) with respect to a joining surface (9) between the bearing housing (4) and the turbine housing (2) or between the bearing housing (4) and the compressor housing (3).Type: GrantFiled: July 22, 2011Date of Patent: July 4, 2017Assignee: BorgWarner Inc.Inventor: Wolfram Schaefer

Publication number: 20040131497Abstract: The present invention relates to a method for inactivating microorganisms especially viruses in protein containing biological compositions, especially blood, placental, serum and plasma components or derivatives solutions of human or animal origin or compositions containing proteins obtained by the extraction of vegetal or animal tissues or obtained by biotechnological techniques, i.e. by culture of natural or recombinant cells of bacterial, yeast, plant or human or animal origin thereby retaining the integrity of the desired protein at a degree suitable for its purpose. By extension the method applies to the inactivation of bacterial or viral preparations, when proteic components or proteic antigens are present, which are intended for use in inactivated or non-living vaccines.Type: ApplicationFiled: September 17, 2003Publication date: July 8, 2004Inventors: Thomas Lengsfeld, Wolfram Schaefer, Thomas Nowak, Michel Grandgeorge
