  • Patent number: 11128061
    Abstract: A method for establishing a materially bonded current path connection in low-voltage, medium-voltage and/or high-voltage installations having long-term stability includes providing a first part and/or a second part of a current path with a nanomaterial at least in one region. The first part and the second part of the current path are force-lockingly or form-lockingly connected at least in the respective regions. A supply of a reaction energy together with the nanomaterial creates a conductive and bonded connection between the first part and the second part of the current path. A low-voltage installation, a medium-voltage installation and/or a high-voltage installation is also provided.

  • Patent number: 10573472
    Abstract: In order to optimize the production of electrical switching contacts, particularly for vacuum tubes, a Field Assisted Sintering Technology process is proposed in which an electrical or electromagnetic field supports and/or produces a sintering process for producing semifinished contact elements for electrical switching contacts, contact elements for electrical switching contacts and/or electrical switching contacts, particularly for vacuum tubes. According to an embodiment, the contact material prior to the sintering process is present in such a form that the material composition of the contact material and/or at least one property of the contact material varies in at least one body direction of the finished contact element.

  • Patent number: 10256054
    Abstract: A method is disclosed for improving the production of electrical switch contacts, in particular for vacuum tubes. In the method, an electrical or electromagnetic field assists and/or effects a sintering process. In the method, the sintering process takes place on a metallic carrier, and via the method, semi-finished contact elements for electrical switch contacts, contact elements for electrical switch contacts, and/or electrical switch contacts, in particular for vacuum tubes, are produced.

  • Patent number: 8869639
    Abstract: A mounting element for receiving a sensor has a sensor receptacle having an essentially cylindrical or funnel-shaped geometry. The sensor receptacle has openings for wetting of the sensor by a medium. The sensor is fixed in the sensor receptacle without gaps or play by a filling compound, which is in turn mounted by a mechanical undercut.

  • Patent number: 8677960
    Abstract: A valve train comprises a double camshaft with an inner camshaft and an outer camshaft. The two camshafts are preferably designed coaxially. By means of a rotatory change in position of the inner camshaft to the outer camshaft, the angular position of at least one cam of the inner camshaft is adjusted or set relative to a cam of the outer camshaft. The cams are divided into sets that can occupy variable cam positions relative to one another. Various configurations of a camshaft adjuster are provided for this purpose.

  • Patent number: 8662040
    Abstract: The invention relates to an oscillating-motor camshaft adjuster having a hydraulic valve, which has two working ports. These two working ports each have a standard opening axially adjacent to one another and an opening for the utilization of pressure peaks as a consequence of camshaft alternating torques. A hydraulic pressure can be guided from a supply port to the working port to be loaded, while the working port to be relieved of pressure is guided to a tank port. In order to also keep the control performance high in the case of internal combustion engines with very greatly fluctuating camshaft alternating torques, it is proposed according to the invention that a position of hydraulic valve can be controlled proportionally, in which the pressure peaks of the working port to be relieved of pressure are blocked relative to the supply port and the working port that is to be loaded.

  • Publication number: 20120235518
    Abstract: The invention relates to an oscillating motor adjuster having a driven stator, which is followed by a first rotor via a first hydraulic power transmission path, which is followed by a second rotor via a second hydraulic power transmission path. The second rotor is joined in a torsionally rigid manner to a second camshaft part, which is disposed coaxially to a first camshaft part, which is joined in a torsionally rigid manner to the first rotor. The relative angular position of the two rotors to one another can be adjusted very accurately by this sequential arrangement of the two rotors.

  • Patent number: 7841311
    Abstract: The present invention provides a variable valve timing device for an internal combustion engine having a double camshaft. A gas exchange valve control shaft is provided which has first and second concentrically arranged cam shafts that are adjustable in a rotatable manner with respect to each other, by which a cam of the first cam shaft is adjusted in terms of its angle towards a cam of the second cam shaft. A cam phasing device is provided which operates by rotatable vanes provoking a swivelling relative movement between a driven member and an output member. The cam phasing device comprises at least two pivotable vane adjusters. Each pivotable vane adjuster is assigned to one of the two cam shafts. The pivotable vane adjusters are arranged axially one after the other in a direction of a valve control shaft. Each pivotable vane adjuster may be designed as a rotor-type vane adjuster.

  • Patent number: 7640902
    Abstract: A camshaft adjuster which operates according to the vane-type motor principle, which means being able to move to and fro within a certain angle, generally comprises a stator and a rotor. The rotor itself is provided as a composite system of at least two components. One of the components is a cover. A further component of the composite system may be denoted as the rotor core. The cover is placed on the rotor.
