Abstract

Schraubenpumpe mit zwei Schrauben (14), bei der jede Schraube (14) ein erstes Gewinde (19) und ein zweites Gewinde (19) aufweist. Die Gewinde (19) erstrecken sich jeweils von einer Saugseite (20) zu einer Druckseite (21) und stehen miteinander in Eingriff, so dass die Gewinde (19) in eine Mehrzahl von Arbeitskammern unterteilt sind, deren Volumen von der Saugseite (20) zu der Druckseite (21) abnimmt. Die Gewinde (19) weisen zwei Gewindegänge auf und das Gehäuse (15) ist mit einer Eingangsöffnung (24) versehen, die größer ist als 60 % der Querschnittsfläche des Gewindes (19).
