Patent ID: 8876644

Claim:
A pump unit with a pump ( 2 ) and with a hybrid drive ( 3 ); the pump comprising a pump housing ( 4 ) and a pump shaft ( 5 ), and the hybrid drive ( 3 ) comprising an electric motor ( 10 ) and a driveshaft connection ( 11 ) to a driveshaft ( 12 ); the electric motor ( 10 ) and the driveshaft connection ( 11 ) are each in driving mechanical functional connection with the pump shaft ( 5 ), by way of a planetary gearset ( 13 ), for driving the pump shaft ( 5 ); a stator ( 15 ) of the electric motor ( 10 ) being at least partially integrated in the pump housing ( 4 ) and a rotor ( 14 ) of the electric motor ( 10 ) being mechanically fixedly connected to a sun gear ( 23 ) of the planetary gearset ( 13 ); the driveshaft connection ( 11 ) being mechanically fixedly connected to a ring gear ( 24 ) of the planetary gearset ( 13 ); and the pump shaft ( 5 ) being mechanically fixedly connected to a planetary carrier ( 25 ) of the planetary gearset ( 13 ).
