Abstract
A pump, particularly a vacuum pump for boosting braking power on a motor vehicle, including a housing, a rotor mounted in the housing so as to be rotatable, an oil riser groove arranged in the housing in the area of the rotor mounting, and a transverse bore arranged in the rotor transverse to the longitudinal axis of the rotor and which can be connected to the oil riser groove. The rotor mounting area is connected to an oil supply bore. The transverse bore interacts with an axial bore in the rotor which leads to a coupling section within the rotor, in which a coupling is arranged which can be engaged by a fastener having a central bore running parallel to the longitudinal axis of the rotor.
