Abstract

Der elektrische Antriebsmotor (1) weist ein Motorgehäuse (3) mit einer Umfangswand (4, 4a) und mit einer vorderen, mit einer eintauchbaren Kreiselpumpe verbindbaren Endwand (5) auf, wobei dem Antriebsmotor ein vom Abwasser beaufschlagbarer Drucksensor (10) zu seinem Einund Ausschalten zugeordnet ist. Zum Schutz des Drucksensors ist dieser in einem in dem Motorgehäuse (3) vorgesehenen Raum (6) angeordnet, wobei zwischen der Umfangswand und einer dieser gegenüberliegenden Fläche (5a) der vorderen Endwand (5) ein zu der Umgebung des Antriebsmotors hin offener Einlaufkanal (11) vorgesehen ist. An den Einlaufkanal (11) schließt sich ein Verbindungskanal (12) an, der wenigstens durch die vordere Endwand (5) hindurch zu dem an diese Endwand angrenzenden Raum (6) des Antriebsmotors verläuft und dort zu dem Drucksensor führt.
