Abstract
An automotive electrical oil pump includes an oil displacement pumping unit with a pump rotor which rotates in a pump chamber so as to pump a pressurized oil to an oil recipient, an electric driving motor which drives the pump rotor of the oil displacement pumping unit, an electrical connector plug which electrically connects the electric driving motor to a power source, and a fluid connector. The fluid connector includes a pump inlet which is fluidically connected to a chamber inlet, a pump outlet which is fluidically connected to a chamber outlet, a center front opening, and a ring front opening which is arranged coaxially to the center front opening. The center front opening and the ring front opening define the pump inlet and the pump outlet.
