Method and device for setting an idle stroke of an actuating drive of an injection valve, and injector assembly

摘要

A method and a device 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.

1. A method for setting an idle stroke of an actuating drive of an injection valve in relation to a control element actuated by the actuating drive, wherein the actuating drive is arranged in an injector body and the control element is arranged in a control-element housing such that the control element is moveable in an axial direction, and the injector body and the control-element housing are arranged in the axial direction with respect to one another, the method comprising:
applying an axial clamping force to the injector body and the control-element housing, such that a part of the injector body or a part of the control-element housing arranged in a force flow path defined by the axial clamping force is permanently deformed, and continuing to apply the axial clamping force to the injector body and the control-element housing until it is determined that a value of a representative electric variable that is determined directly or indirectly for the idle stroke of the actuating drive is within a predetermined range of values.
