Publication number: 20220316433Abstract: A fuel rail for a fuel injection system of a vehicle comprises a distributor pipe extending along a longitudinal axis, having at least one inlet connection for connection to a fuel pump and a plurality of outlet connections for connection to one injector each, which injectors are arranged along the longitudinal axis at a distance from the inlet connection, and a support projection which is arranged between the inlet connection and the outlet connections relative to the longitudinal axis, which projection protrudes in a radial direction extending transversely to the longitudinal axis into an interior of the distributor pipe. The fuel rail further comprises a throttle piece arranged in the interior of the distributor pipe, having a through-opening extending between a first and a second end face, which through-opening has a diameter which is smaller than an inside diameter of the distributor pipe on opposite sides of the support projection in each case.Type: ApplicationFiled: April 6, 2022Publication date: October 6, 2022Inventor: Joerg Jennes

Patent number: 11199220Abstract: The invention relates to an exhaust-gas-driven turbocharger having a hydrodynamic plain bearing having a rotor and a stator, the rotor being rotatable with respect to the stator, the rotor bearing surface being located opposite a counter-surface of the stator in order to generate hydrodynamic pressure in the region of a converging gap. In such a hydrodynamic plain bearing, the application properties can be improved by the fact that the rotor bearing surface and/or the counter-surface constitutes in a section view, in the context of a section along and through the rotation axis, a continuous bearing contour that is constituted from convex or concave curvatures and/or from at least two contour segments that are embodied as straight lines and/or curvatures. The invention also relates to a hydrodynamic plain bearing or bearing arrangement having such a plain bearing.Type: GrantFiled: April 30, 2020Date of Patent: December 14, 2021Inventors: Martin Berger, Rüdiger Kleinschmidt, Martin Kropp, Jörg Jennes

Patent number: 7114919Abstract: A guiding grid of variable geometry for turbines comprises a turbine housing and a plurality of guiding vanes in the housing in angular distances around a central axis. Each vane is pivotal about an associated pivoting axis to assume different angles in relation to the central axis and, thus, to form a nozzle of variable cross-section between each pair of adjacent vanes. A generally annular nozzle ring supports the adjustment shafts of the guiding vanes. A unison ring is displaceable around the central axis relative to the nozzle ring. This unison ring is operatively connected to the vanes via a transmission mechanism in order to pivot them when being displaced to adjust their respective angular position in relation to the central axis. The transmission mechanism comprises a first transmission element with an opening and a second transmission element slidably engaging this opening.Type: GrantFiled: November 12, 2003Date of Patent: October 3, 2006Assignee: Borgwarner, Inc.Inventors: Georg Scholz, Joerg Jennes
