摘要： A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.

摘要： The invention relates to a valve for a fuel injection system, having a valve seat embodied in a valve housing, and having a valve member which is movable in the valve housing and has a sealing face that when the valve is closed rests sealingly against the valve seat and when the valve is open, together with the valve seat, defines a valve gap through which fuel flows. To prevent cavitation damage, the valve member has an encompassing hollow throat, which is disposed in the flow direction immediately downstream of the sealing face and is adjoined by an encompassing cross-sectional thickening of the valve member.

摘要： A method for bounce suppression of a valve member operated by a piezo actuator during the closing phase of a valve in an internal combustion engine, having the following steps: partial discharging of the piezo actuator, whereby the valve member is braked even before reaching the valve seat, interruption of the discharge of the piezo actuator, whereby the piezo actuator is upset by the valve member and builds up an electric charge, renewed discharging of the piezo actuator, the residual charge after partial discharge and the charge built up during the charge interruption being at least partially dissipated. It is provided, according to the present invention, briefly to interrupt the discharge process, whereby the piezo actuator absorbs the energy of the valve member and, even before an elastic rebound takes place, the piezo actuator is discharged again, in order to dissipate the energy absorbed by the piezo actuator.
