Summary:The invention relates to an actuator unit, which comprises a piezoactuator (1) having a first end face (14') and a second end face (13'). The actuator unit further comprises a sleeve (9) for accommodating the piezoactuator (1), wherein the sleeve (9) has a first end face (14) and a second end face (13). The actuator unit further comprises a potting compound (11) which surrounds the piezoactuator (1). The piezoactuator (1) and the potting compound (11) are introduced into the sleeve (9). The potting compound (11) extends no further than the first end face (14') of the piezoactuator (1). The invention further relates to a method for manufacturing an actuator unit and a sleeve for accommodating a piezoactuator.
