Abstract

An actuating drive for an injection valve may comprise: a sleeve-shaped actuator housing; an actuator unit disposed in the housing; at least one actuator feed line; at least one connector contact; a housing unit; a cover; and a first sealing unit. The at least one actuator feed line may protrude from an end-side opening of the actuator housing. The at least one connector contact may be coupled electrically to the at least one actuator feed line and configured to be coupled electrically to a system-side connector. The housing unit may be arranged along a circumference of the actuator housing in an end-side shell surface section of the actuator housing and configured to fix the at least one connector contact in a predefined position. The cover may close a cavity defined by the housing unit and be coupled mechanically to the housing unit. The first sealing element may be arranged between the housing unit and the cover to prevent penetration of solid, liquid, or gaseous media into the cavity.
