Abstract
A hydraulic pressure supply unit has a storage chamber which stores hydraulic fluid, a hydraulic pump which is arranged within the storage chamber and dips at least partially into the stored hydraulic fluid, and an electric motor which drives the hydraulic pump. The electric motor is arranged below the hydraulic pump in a separate motor chamber which is situated below the storage chamber, is dry, and is not connected fluidically to the storage chamber. The electric motor is coupled in a thermally transmitting manner to a separating floor, the upper side of which delimits the storage chamber and is wetted continuously with stored hydraulic fluid.
