Abstract
The disclosure relates to an electric-motor-driven hydraulic pump actuator with two plate-like housing elements which are connected sealingly to one another with the interposition of an intermediate plate in order to form a housing in which a drive shaft is rotatably mounted.In order to improve the functionality and/or simplify manufacture of the electric-motor-driven hydraulic pump actuator, a bearing device for the drive shaft is secured in one of the housing elements by means of a spring device that passes through the intermediate plate via a through-hole through which the drive shaft extends.
