Actuators for driving a valve unit of an internal combustion engine, having an electric motor (26), having a gearing (28) which is driven by the electric motor (26) and having a gearing housing (30) in which the gearing (28) is arranged, wherein the gearing housing (30) has a first gearing housing part (32) out of which a drive output element (16) of the actuator (12) extends, are known. Aside from an excessive installation space requirement, problems often arise owing to vibrations or overly complex assembly. To solve this problem, it is proposed according to the invention that the gearing housing (30) has a gearing housing cover (34) to which the electric motor (26) is fastened and in which a bearing (82) of the electric motor (26) is fastened axially and radially. |
