Abstract
(DE)

[Aufgabe] Es wird ein Scrollverdichter vorgeschlagen, der eine verbesserte Bearbeitbarkeit ermöglicht, wenn eine Gegendruckkammer und eine Verdichtungskammer miteinander verbunden sind. [Lösung] Ein Scrollverdichter 1 weist eine Gegendruckkammer 39, die in einer hinteren Oberfläche einer Spiegelplatte 31 einer beweglichen Schnecke 22 in dem Scrollverdichter 1 ausgebildet ist, und ein Verbindungsloch 51 auf, das in der Spiegelplatte 31 der beweglichen Schnecke 22 ausgebildet ist und die Gegendruckkammer 39 und eine Verdichtungskammer 34 miteinander verbindet. Das Verbindungsloch 51 besteht aus einem Lochabschnitt mit großem Durchmesser 52, der sich auf der Seite der Gegendruckkammer 39 der Spiegelplatte 31 der beweglichen Schnecke 22 befindet, und einem Lochabschnitt mit kleinem Durchmesser 53, der sich von dem Lochabschnitt mit großem Durchmesser 52 fortsetzt, um die Verdichtungskammer 34 zu erreichen.
