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.

摘要： The invention relates to a common rail injector for injecting fuel in a common rail injection system of an internal combustion engine, which system has an injector housing (1) with a fuel inlet (24) that is in communication with a central high-pressure fuel reservoir outside the injector housing (1) and with a pressure chamber (27) inside the injector housing (1), from which fuel subjected to high pressure is injected as a function of the position of a control valve (18) that assures that a nozzle needle (8), which is movable back and forth and received in a longitudinal bore (6) of the injector axially counter to the prestressing force of a nozzle spring (21) that is received in a nozzle spring chamber (20), lifts from a seat when the pressure in the pressure chamber (27) is greater than the pressure in a control chamber (30) that communicates with the fuel inlet (24) via an inlet throttle (19). To achieve markedly higher nozzle needle speeds, the control chamber (15) is formed by a cylindrical chamber, in which a control peg (12), embodied on the end of the nozzle needle (8) remote from the combustion chamber, is displaceable causing a sealing effect, and that the nozzle spring chamber (20) is disposed outside the control chamber (15), in the region of the end of the nozzle needle (8) remote from the combustion chamber.

摘要： The fuel injection valve (16) has an injection valve member (24), by which at least one injection opening (26) is controlled. The motion of the injection valve member (24) is influenced by a control valve (18), which has a control valve member (62) by which the pressure in a control pressure chamber (48) is controlled and which is movable by an adjusting force generated by a piezoelectric actuator (80) and in the process control the communication of the control pressure chamber (48) with a relief chamber (12). The control valve (18) has two valve seats (60, 74), spaced apart from one another in the direction of motion of the control valve member (62), with which seats the control valve member (62) cooperates, each with a respective sealing face (66, 69) disposed on it, so that the control valve member (62) has two closing positions, in which the control pressure chamber (48) is disconnected from the relief chamber (12). When the control valve member (62) is not in one of the two closing positions, the control pressure chamber (48) does communicate with the relief chamber (12). With a motion of the control valve member (62) between its two closing positions, a brief opening of the fuel injection valve (16) is made possible.
摘要翻译：燃料喷射阀（16）具有喷射阀构件（24），通过该喷射阀构件控制至少一个喷射开口（26）。喷射阀构件（24）的运动受控制阀（18）的影响，控制阀（18）具有控制阀构件（62），通过该控制阀构件控制控制压力室（48）中的压力，并且其可通过调节由压电致动器（80）产生的力，并且在过程中控制压力室（48）与释放室（12）的连通。控制阀（18）具有两个阀座（60,74），它们在控制阀构件（62）的运动方向上彼此间隔开，控制阀构件（62）与其配合，设置在其上的相应的密封面（66,69），使得控制阀构件（62）具有两个关闭位置，其中控制压力室（48）与释放室（12）断开。当控制阀构件（62）不处于两个关闭位置中的一个时，控制压力室（48）与释放室（12）连通。随着控制阀构件（62）在其两个关闭位置之间的运动，燃料喷射阀（16）的简单开口成为可能。
