Abstract

Die vorliegende Erfindung betrifft eine Scrollpumpe mit einem Gehäuse und einem in dem Gehäuse befindlichen Orbiter, der eine Trägerplatte und eine sich von der Trägerplatte erstreckende Spirale aufweist. In der Trägerplatte sind mehrere Durchgangsöffnungen ausgebildet, durch die ein Gehäusebereich, der sich auf einer der Spirale des Orbiters abgewandten Seite der Trägerplatte befindet, für ein Werkzeug zu Montagezwecken zugänglich istThe present invention relates to a scroll pump with a housing and an orbiter located in the housing, which has a carrier plate and a spiral extending from the carrier plate. A plurality of through openings are formed in the carrier plate, through which a housing area, which is located on a side of the carrier plate facing away from the spiral of the orbiter, is accessible to a tool for assembly purposes
