    摘要： The invention relates to an actuator (1) comprising a housing (8), a coil (29) and an armature (2) which interacts with a tappet (30) and a spring, the armature plate (3) thereof being arranged to lie opposite an armature counterpiece (16), and said actuator (1) comprising at least one magnetostrictively-active component. According to the invention, an actuator (1) is provided with which large actuating paths can be travelled at high actuating forces. This is achieved by the actuator (1) additionally being designed to act as a solenoid.

    摘要： A piezoelectric actuator module having a multilayer structure of piezoelectric elements (3) is proposed as a piezoelectric actuator (2), wherein a different polarity of an electric voltage is alternately applied to inner electrodes which are arranged between piezoelectric layers of the piezoelectric elements (3) in the direction of the layer structure of the piezoelectric elements (3), said module having an actuator foot (4) and an actuator head (5) composed of steel and having an elastic insulation medium which surrounds at least the piezoelectric elements (3) in predefined limits. At least one annular groove (11;24) or recess (14), into which a material (12) which can be crosslinked with the insulation medium is vulcanized, is provided on the actuator foot (4) and/or on the actuator head (5), and a flexible, weldable hose (9) lies above the piezoelectric element (3) and at least above the grooves (11;24) or recesses (14) containing the material (12) as an insulation medium and is welded to the material (12) in the grooves (11) or recesses (14).

    摘要： A fuel injector for an internal combustion engine is proposed having a directly actuable injection valve element. The fuel injector has a nozzle needle (13), axially guided in a nozzle body (12), and an actuator (20) accommodated in an injector housing (10), wherein the nozzle needle (13) is connected to a coupling piston (34) on the nozzle-needle side and the actuator (20) is connected to a coupling piston (21) on the actuator side. The coupling piston (21) on the actuator side acts on a coupling space (32) and the coupling piston (35) on the nozzle-needle side acts on a control space (38), wherein the nozzle needle (13) is lifted from a nozzle-needle sealing seat (14) as a function of the pressure in the control space (38). Provided between injector housing (10) and nozzle body (12) is an intermediate plate (40) having a passage (50) which hydraulically connects the coupling space (32) to the control space (38). The passage (50) contains a hydraulic choke (51) which has at least two sections (52, 53) having different cross sections of flow, wherein the section (52) having the smaller cross section of flow faces the coupling space (32) and the section (53) having the larger cross section of flow faces the control space (38).
