Abstract:
An actuating drive comprising a housing which has a first housing portion and a second housing portion, wherein:the two housing portions each have a respective edge with a respective end face and the two end faces are in mutually opposite relationship when the two housing portions are assembled; the first housing portion and the second housing portion can be releasably and directly assembled together; when the two housing portions are assembled, first, second and third zones which act in different ways are formed between the two end faces; the first zone in which the two housing portions are in contact with each other is formed on the housing towards the exterior; the second zone has a passage and is formed beside the first zone towards the interior; and the passage of the second zone in the housing is closed towards an internal space of the housing by the third zone in which the two housing portions are not in contact with each other, and the spacing between the two housing portions in the third zone is such that any water present in the second zone, by virtue of surface tension effects, cannot flow beyond the third zone into the internal space of the housing.
