  • Valve train device
    Patent number: 8474421
    Abstract: In a valve drive train device, in particular for a valve drive of an internal combustion engine, with a switching unit comprising an actuator with a solenoid unit and with a control unit for monitoring switching operations of the switching unit provided for switching an axially displaceable cam element by means of a switch gate, the control unit for monitoring the switching unit is taking into account at least one characteristic value of a voltage integral over a voltage which is induced in a coil of the switching unit during the switching operation and is adjusting the value with respect to a characteristic limit value stored in the control unit.
    Type: Grant
    Filed: November 5, 2010
    Date of Patent: July 2, 2013
    Assignee: Daimler AG
    Inventors: Matthias Gregor, Richard Jakobi
  • Camshaft unit
    Patent number: 8474422
    Abstract: In a camshaft unit, particularly of an internal combustion engine, comprising a camshaft connected to a drive unit to be driven thereby, a phase displacement unit including an actuating gear and a control unit with a rotor and a stator unit in the form of a brake element for adjusting a phase relation between the drive unit and the camshaft, and a bearing device for supporting part of the control unit, the bearing device is designed to accommodate radial tolerances between the stator element and the rotor element.
