Claims (8)
dass die axiale Verlagerung der Rotorwelle (3) in Öffnungsrichtung durch ein mit dem Gehäuseunterteil (4) verbundenes kapselartiges Gehäuse oberteil (2) begrenzt ist, das auf seiner in Öffnungsrichtung liegenden Oberseite eine angepasste Durchführöffnung (2.1) für einen in seinem Durchmesser gegenüber dem Durchmesser des Gewindeabschnitts (3.2) verjüngten Wellenabschnitt (3.3) aufweist, und
dass die Rotorwelle (3) mit seiner auf der Seite des Gewindeabschnitts (3.2) liegenden Stirnseite unmittelbar auf den elastischen Bereich (5) einwirkt.3. Vacuum suction device according to claim 2, characterized in
that the axial displacement of the rotor shaft ( 3 ) in the opening direction is limited by a capsule-like housing upper part ( 2 ) connected to the lower housing part ( 4 ), which on its upper side lying in the opening direction has an adapted through opening ( 2.1 ) for a diameter compared to the diameter of the threaded section ( 3.2 ) has a tapered shaft section ( 3.3 ), and
that the rotor shaft ( 3 ) acts directly on the elastic region ( 5 ) with its end face lying on the side of the threaded section ( 3.2 ).
