Abstract:
1. An elastomer sealing element that can be plugged onto the head plate of a piezo actuator for a fuel injection valve of an internal-combustion engine, in which case the piezo actuator is provided to be fitted in the injector body of an injection engine, the sealing element comprising: at least one encircling sealing bead formed on a middle portion of the sealing element by means of which the sealing element is inserted into the injector body; at least one breakthrough for accommodating a contact pin which passes through the sealing element in a longitudinal direction, wherein the breakthrough is sealed by a sealing lip, wherein the sealing lip is formed on a distal end of the sealing element; and a grommet portion forming a proximal end of the sealing element opposite the distal end, wherein the sealing element can be plugged into the head plate of a piezo actuator by means of the grommet portion, wherein the grommet portion is radially larger than the encircling sealing bead and the sealing lip.
