Abstract

Um einen Schraubenverdichter umfassend ein Gehäuse mit einer Läuferkammer, zwei in der Läuferkammer angeordnete Schraubenläufer, einen an die Läuferkammer angrenzenden Schieber zur Leistungssteuerung, eine Stelleinrichtung, umfassend einen Zylinder sowie eine zugeordnete Steuereinrichtung mit welcher in einem stufenlosen Steuermodus ein Zufluß und ein Rückfluß des zum Betätigen des Zylinders vorgesehenen Mediums steuerbar ist, derart zu verbessern daß die Steuereinrichtung zuverlässig arbeitet, wird vorgeschlagen, daß die Zylinderkammer eine Rückflußöffnung und eine Zwischenrückflußöffnung aufweist, und daß die Steuereinrichtung in dem Steuermodus zur stufenlosen Steuerung in einem Teilsteuerbereich zwischen einer Zwischenstellung und einer Minimalstellung die Rückflußöffnung aktiviert und zur stufenlosen Steuerung von Kolbenstellungen außerhalb des Teilsteuerbereichs die die Zwischenstellung festlegende entsprechende Zwischenrückflußöffnung aktiviert.
