  • Piezoelectric actuator with a sheathing composed of a composite material
    Patent number: 8261720
    Abstract: A piezoelectric actuator for flowing-around media, with a piezo element arranged between two end caps. The piezo element is surrounded by a ring-shaped sheathing connected to the end caps. The sheathing consists, at least in portions, of a composite material with at least two layers, at least one layer consisting of a metallic material and at least one layer consisting of a polymer.

  • FLAT SEAL
    Publication number: 20110101626
    Abstract: The invention relates to a flat seal, in particular a cylinder head gasket or an exhaust flange seal, comprising at least one layer provided with at least one through opening. The through opening receives at least one elastically deformable profiled body configured as an annular profile wire, having a defined material thickness. The total height of the non-deformed profiled body is greater than the thickness of the layer, and the layer is provided at least partially with material thickening in the region of the profiled body and/or outside of the profiled body.

  • FLAT SEAL
    Publication number: 20110101623
    Abstract: A flat seal, in particular a cylinder head gasket or an exhaust flange seal, includes at least one layer provided with at least one through opening. The through opening receives at least one elastically deformable profiled body configured as an annular profile wire. The profiled body, when seen in the radial direction, has different material thicknesses and is functionally connected to at least one support body.
