Beschreibung
Zusammenfassung:	Lock for a vacuum chamber (6) which lock has a passage comprising an outer sealing means (2) and an inner sealing means (3) which outer sealing means can be maintained in the closed position under the influence of the pressure difference caused by the vacuum in the vacuum chamber, and can be opened against the force caused by said pressure difference, which inner sealing means can be maintained in the opened position under pretension and comprises closing means (4,5) for closing the inner sealing means against said pretension. The closing means comprise at least one electromagnet (4).
