摘要： A method and a device are disclosed for setting an idle stroke of an actuating drive of an injection valve with respect to an actuating element actuated by the actuating drive. The actuating drive is arranged in an injector body and the actuating element is arranged in an actuating-element housing such that it is movable in an axial. An axial stressing force is applied to the injector body and the actuating-element housing such that part of the injector body or actuating-element housing arranged in a force flow path defined the axial stressing force is deformed permanently, until a value of a representative electric variable determined directly or indirectly for the idle stroke of the actuating drive lies in a predefined value range. Further, an injector assembly for an injection valve may include an injector body and/or an actuating-element housing having a contact section elevated in the axial direction.

摘要： An injector has a valve pin whose position is adjustable according to the pressure prevailing in a control chamber and which blocks a fluid flow through at least one injection port in a closed position. The injector has a control chamber that is hydraulically coupled to a high-pressure fluid reservoir, a piezo actuator, and a control valve which hydraulically connects and disconnects the control chamber, the piezo actuator acting upon said control valve. A combination of a triggering period for the piezo actuator and electric power that is to be fed to the piezo actuator is varied from a predefined initial combination to a target combination in which a pressure curve is detected that is characteristic of a movement of the control valve out of the closed position thereof without fluid being proportioned through the injection port.

摘要： In a driving configuration for driving an actuator, component tolerances are compensated for by measuring a discharging current flowing in a measuring branch and the discharging voltage during a charge-transfer (reversing) operation. The measuring branch contains a series resonance circuit having a charging capacitor, a coil, an auxiliary switch and a measuring resistor. The current and voltage values measured at various instants are evaluated; and from them, initial parameters are determined for the subsequent driving operations.

摘要： A capacitive control element is charged with a defined charging voltage Uc. From a stored mapping KF, the instantaneous control element capacitance Cp is determined from the charge voltage Uc and a control element voltage Up. In addition, energy E supplied to the control element is determined from the charge voltage Uc and the control element capacitance Cp. According to a deviation of energy E fed to the control element from a stipulated amount of energy Ev, the charge voltage Uc for a next drive process of the control element is regulated. The same process occurs for additional control elements.
