  • Patent number: 8720852
    Abstract: The positioning of the actuating drive in a fuel injector with a piezoactuator (2) that is screwed into the housing (1) of the fuel injector is performed by applying a voltage (U) to the piezoactuator (2) that corresponds to a given idle stroke (h), and the surface grinding of the housing (3) and base plate (4) of the piezoactuator (2) when voltage is applied. Between the housing (1) of the fuel injector and the housing (3) of the piezoactuator (2), there is also provided a compensation collar (9) of a suitable thickness.

  • Patent number: 7351829
    Abstract: The invention relates to compounds based on merocyanines with the general formulas I and/or II, where n=0 or an integer from 1 to 3, X=O or S and the residues R1 to R12 are the same or different and signify in particular hydrogen or various organic residues, without or with functional groups, and R2 incorporates an amine function. The compounds in accordance with the invention are suitable as fluorescent dyes (fluorophores) for used in optical determination and demonstration methods, in particular those employing fluorescence, for example in medicine, pharmacology and the biological, materials and environmental sciences. They are characterized by high photostability and long storage life, and exhibit a high fluorescence quantum yield. Excitation causing them to emit light can be achieved in a simple manner, by white-light sources or by laser irradiation in the UV, visible or NIR spectral region.

  • Patent number: 7052361
    Abstract: In a method for the hydro-erosive rounding of an edge of a part, particularly an edge in a duct of a high pressure-resistant part, and a use thereof, a liquid to which abrasive elements are added is directed along the edge that is to be rounded. In order to optimize the result of the rounding process, a high-viscosity liquid is used as a liquid (10). The inventive method is used for rounding parts of a fuel injection system.

  • Patent number: 7009134
    Abstract: An electrode guide and a method for the spark-erosion of workpieces are disclosed. The electrode guide (1), consisting of a two-piece prism-shaped (2, 3) guide with a pretensioning device (6), enables an electrode (4) to be guided in a play-free manner, thus allowing the production of bores that is accurate to within 1 ?m. A pivoting device (10) for pivoting the electrode guide and an alignment device (14) for the parallel displacement of the electrode guide (1) are also provided, enabling the production of conical bores.

  • Patent number: 6998761
    Abstract: A piezoelectric assembly, a method for producing a structural unit with a prestressed piezoelectric actuator and a method for producing a hollow body for prestressing the piezoelectric actuator include an actuator pushed into a spring sleeve and force-lockingly and/or form-lockingly connected under prestress to two ends of the spring sleeve. This provides a structural unit in which the prestressing force of the piezoelectric actuator is permanently fixed by the production process.

  • Patent number: 6787973
    Abstract: A device for transmitting the deflection of an actuator (2), comprising at least one transmission element (4) that has a first, a second and a third support zone, said first support zone (6) being associated with a counter-support, said second support zone (8) being associated with the actuator, and said third support zone being associated with a control element (20). The at least one transmission element rests on the counter-support with the first support zone under the action of the actuator and displaces the control element with the third support zone by way of a rotational movement about a center of rotation. The at least one transmission element is substantially configured as a plate (5) that is disposed substantially perpendicular to the movement of adjustment and the first, the second and the third support zone are configured as substantially plane surfaces on the plate, further relates to a method for producing the inventive transmission element.

  • Patent number: 6681462
    Abstract: A method for producing a structural unit with a prestressed piezoelectric actuator includes the steps of inserting a front end of the actuator into a hollow body, form-lockingly or force-lockingly connecting the inserted front end of the actuator to the hollow body, pressing the actuator into the hollow body with a defined force establishing a prestress of the actuator, and force-lockingly or form-lockingly connecting the actuator to the hollow body in the vicinity of a rear end of the actuator, for fixing the prestress of the actuator.

  • Patent number: 6607178
    Abstract: A device for transferring a thrust, a fuel injection valve with such a device, and a method for manufacturing such a thrust transferring device. To transfer the thrust of an actuator, especially in an injection valve, mechanical tappets are used, which have substantially the shape of a cylinder whose defining surfaces are substantially triangular, with the corners rounded. By the great width of the tappet, broad contact areas are created so that friction during the transfer is reduced.
