Abstract
A liquid pump has a housing with a suction connection, a pressure connection and a electric motor for rotationally driving a conveying device that has a suction inlet and pressure outlet which communicate with the suction connection and the pressure connection respectively. An electronic power unit for the electric motor is adjacent to the motor and extends transversely to the axis of rotation and is on the rear side of the partition wall of the housing. The suction inlet is arranged at a height smaller than an inner radius of an annular gap between the stator and rotor, whereas a rotor passage extends at a constant height, so that a liquid inducted by way of the suction connection is guided in part via the annular gap and undergoes a deflection at the partition wall, cooling the latter before it passes through the rotor passage to the suction inlet.
