ABSTRACT:
The invention relates to a new type of hydraulic module for actuating at least one hydraulic control element with a hydraulic pump in a housing, with an electric motor fastened to a first housing side for driving the pump, with a tank located on a second housing side opposite the first side for a hydraulic fluid, e.g. hydraulic oil, with flow channels produced in the housing produced preferably by bore holes for the hydraulic fluid to supply this fluid from the tank to a pump chamber, for transmitting the hydraulic fluid conveyed by the pump to a pressure connection located on the housing, for connection of the at least one actuating element and for returning the hydraulic fluid from the pressure connection into the tank.
