摘要： A piezoelectric actuator is described, for example for actuating a mechanical component, in which a piezoelectric element that produces tensile or compressive force acting on an actuation element is provided. The piezoelectric element has a multi-layer structure of piezoelectric layers with internal electrodes (2, 3) disposed between them. The contacting of the internal electrodes (2, 3) on alternate sides takes place by means of external electrodes (10, 11).

摘要： A piezoelectric actuator for actuating a mechanical component, having a multilayered structure of piezoelectric layers with inner electrodes disposed between them and contacting outer electrodes on alternating sides and the piezoelectric actuator has chamfered corners or edges. In the region of the corners or edges, on the sides of the piezoelectric actuator on which the inner electrodes with alternating polarities are routed to the respective outer electrodes, the inner electrodes have a contour that makes it possible to achieve a lower field intensity between the inner electrodes of alternating polarities in the structure of piezoelectric layers. This is achieved by virtue of the fact that on the side that does not contact the outer electrodes, the edge has an obtuse angle (∝) or is rounded.

摘要： The invention relates to a fuel injection valve that has a valve member which can control a fuel outlet opening. The valve member has a first opening surface, which defines a first opening pressure chamber in the opening direction of the valve member, wherein the first opening pressure chamber is connected to a high-pressure fuel source and the pressure in the first opening pressure chamber produces a first opening force against the first opening surface. The valve member also has a first closing surface, which defines a first closing pressure chamber in the closing direction of the valve member, wherein the first closing pressure chamber is connected to the high-pressure fuel source and the pressure in the first closing pressure chamber produces a first closing force against the first closing surface.

摘要： A fuel injection valve for an internal combustion engines is proposed, in which the control of the fuel injection valve member is controlled through the control of the pressure of a control chamber (25). This chamber is either relieved by means of a control valve (31) or is subjected to a high pressure, which brings the fuel injection valve member into the closed position. At the same time as the relief of the control chamber, a valve member (33) of a safety valve (32) that controls the fuel supply to the fuel injection valve is opened so that upon opening of the fuel injection valve, high-pressure fuel simultaneously also can travel by way of a pressure line (12) from a high-pressure fuel reservoir (14) to the injection openings (8) of the fuel injection valve (1). After the end of the injection, the valve member (33) is closed again, together with the closing of the fuel injection valve member (5). Consequently, in the event of a malfunction, unwanted fuel is prevented from reaching injection for a long period of time and consequently possibly destroying the associated engine due to overdosing.

摘要： A piezoelectric actuator in which a piezoelectric element is present for subjecting an actuating element to a tensile or compressive stress. A sleeve is secured to a foot part, to which the piezoelectric element is secured and by way of which the piezoelectric element is kept centered in a housing under mechanical prestressing, and this sleeve surrounds the piezoelectric element in such a way as to stabilize it mechanically, at least in partial regions that are electrically insulated from the piezoelectric element. Between the sleeve and the piezoelectric element, a heat-conducting elastomer is placed, and the sleeve comprises a heat-conducting material that is deformable within predetermined limits.

摘要： A piezoelectric actuator for actuating control valves or injection valves in motor vehicles. The actuator includes an actuator body in the form of a multilayer laminate of stacked layers of piezoelectric material and intervening metallic or electrically conductive layers acting as electrodes. One bottom plate toward the valve and an opposed top plate are mounted on each of the end faces of the actuator body. The piezoelectric actuator is characterized in that the actuator body on each of its end faces has one piezoelectrically inactive cover layer and that the connection faces of the bottom plate and the top plate which adjoin the end faces of the actuator body have fixation elements that grip the cover layers, for at least nonpositive fixation of the cover layers of the actuator body.
