The electromotor ( ) has a motor stator ( ) in which a motor rotor ( ) is rotatably disposed. The pump ( ) is disposed substantially within the motor rotor ( ) and can be driven by the latter. In order to provide a vehicle brake system with a motor/pump unit ( ) which is capable of delivering brake fluid in a highly dynamic fashion, the motor stator ( ) and at least one section ( ) of the motor rotor ( ) which is directed towards the motor stator ( ) define an electromagnetic region ( ), and at least the pump ( ) defines a hydraulic region ( ), wherein at least one sealing element ( ) is provided which separates the electromagnetic region ( ) from the hydraulic region ( ) in a fluid-tight fashion.
