Beschreibung
Zusammenfassung:	A pump device (10) having a drive shaft (12) which has a drive section (14) that can be coupled with a drive system is provided. The pump device (10) includes a vacuum pump (15) that can be driven by the drive shaft (12). The vacuum pump (15) includes a rotor (16) and at least one blade (18, 20) that can be moved in radial direction in the rotor (16) and that divides pressure chambers. The pump device (10) also includes a lubrication pump (26) that can be driven by the drive shaft (12). The vacuum pump (15) is arranged between the drive section (14) and the lubrication pump (26). A locking device (36) is provided between the rotor (16) and the lubrication pump (26) in which, when activated, the at least one blade (16, 20) remains in a radially internal position when the rotor (16) is rotating.
