Motor-pump assembly, in particular for a vehicle braking system

The device has an electric motor (1) driving a coaxial pump (2), a universal joint connection between the motor and pump via a coupling part (6) with a shape-locking plug-in holder for a driven side rotor shaft end (4) of the motor and drive side pump shaft end (5), a conical plug-in holder shape and mutual axial biasing of the rotor and pump shaft ends in the sense of a play free drive
