Abstract
A pumping device for pumping oil in a transmission system of a hybrid drive for a motor vehicle has an oil pump and a direct drive for driving the rotor and an electric drive for driving a rotor part that surrounds the rotor. A stationary housing surrounds the rotor part and has an inlet connection and an outlet connection of the oil pump. The oil pump allows a selective drive via the direct drive or the electric drive in a simple manner.
