    摘要： A tubular spring is provided for receiving and pretensioning a piezoelectric or magnetostrictive actuator of an actuator unit, e.g., for actuating a fuel injector valve in internal combustion engines, wherein the tubular spring comprises at least two types of recesses, each comprising different maximum lateral extensions in the longitudinal direction of the tubular spring. The tubular spring is designed to comprise a uniform load distribution about the circumference of the tubular spring even without welding the longitudinal sides thereof abutting one another.

    摘要： The present invention provides an apparatus that can form a plurality of orifices where the orifices are consistent dimensionally, such as, for example, the diameter, the surface roughness or the entry and exit configurations. Preferably, the invention provides a laser machining apparatus. The apparatus includes a laser light source that provides a generally coherent light beam along the beam's axis. The apparatus also includes a light directing device to direct a first portion of light from the light beam to a work piece at a first angle of incidence relative to the axis of the light beam during a first time interval to form at least one of an orifice and a chamfer. The apparatus further includes an adjustable beam splitter assembly to direct another portion of the light beam to form the other of the at least one of an orifice and a chamfer in the work piece during a second time interval that overlaps a portion of the first time interval. The method includes providing at least a first beam and a second beam that are emitted from the laser light source towards the workpiece; and rotating at least a first beam and a second beam with respect to the longitudinal axis. The method further includes forming at least one orifice in the workpiece with at least one of the first and second beams during a first time interval; and forming the at least one chamfer in the workpiece with the other of the first and second beams during a second time interval that overlaps a portion of the first time interval.

    摘要： In the operation of piezoactuators of multilayer construction, during the polarizing or during the operation of the piezoactuator tears can arise, due to voltages, in the metallization strips that are attached to the actuator on the outside for contacting the electrode layers. It is inventively proposed to install electrically conductive contact lugs directly at the stack or on the metallization strips such that a laterally protruding region remains, so that, even given arising tears, these nevertheless extend in the protruding region of the contact lug, and the tears are electrically bridged. Electrical terminal elements are provided so as the project above or laterally at the contact lugs.
