Abstract
The invention relates to a method for producing an actuator unit comprising a piezoactuator (), a sleeve () having a first end face () and a second end face (), and a potting compound (). The method comprises: inserting the piezoactuator () into the sleeve (), wherein the piezoactuator is inserted into the sleeve () from the side of the sleeve () having the first end face (); arranging a filling opening of a filling element () in an axial position near the axial position of the second end face () of the sleeve (); filling a hollow space between the inner side of the sleeve () and the piezoactuator () with the potting compound () via the filling opening of the filling element (), such that the potting compound () extends maximally to a first end face (') of the piezoactuator (). The invention further relates to a sleeve () for receiving a piezoactuator ().
