Claim 0:
1. A hydraulic pressure supply unit, comprising:
a hydraulic fluid reservoir having a stored hydraulic fluid therein;
a partition base having an upper side which delimits the hydraulic fluid reservoir and is constantly wetted with the stored hydraulic fluid;
a separate motor compartment located below the hydraulic fluid reservoir, the motor compartment being dry and not in fluid communication with the hydraulic fluid reservoir;
a hydraulic pump arranged within the hydraulic fluid reservoir and at least partially immersed in the stored hydraulic fluid;
an electric motor driving the hydraulic pump, the electric motor being arranged below the hydraulic pump in the motor compartment, the electric motor being coupled in a heat-conducting manner to the partition base;
at least one electrical component accommodated in the motor compartment; and
a housing part which circumferentially delimits the hydraulic fluid reservoir, the partition base being connected in a heat-conducting manner to the housing part;
a ventilation bore which communicates on the one hand with the motor compartment and on the other hand with the ambient surrounding environment;
wherein the partition base forms a carrier plate in which hydraulic functionalities are integrated by means of built-in elements, wherein the built-in-elements comprise valves;
wherein the partition base is circumferentially accessible at a circumferential surface;
wherein the partition base comprises fluid connections arranged on the circumferential surface of the partition base, wherein the fluid connections comprise a pressure connection and a tank connection;
wherein the ventilation bore extends inside the partition base and opens at the circumferential surface thereof.
