Abstract

Die Erfindung betrifft ein Antriebselement für Wasser­ fahrzeuge, insbesondere Schiffe, mit auf einer aus dem Schiffsrumpf herausragenden Antriebsachse befestigten, in einem bestimmten Winkel dazu ausgerichteten Schrau­ benflügeln (3), die von einem Zylindermantel (4) umgeben sind. Das Antriebselement ist dadurch gekennzeichnet, daß auf der Antriebsachse (1) im Abstand (L) von den Schraubenflügeln (3) in Richtung des Antriebsmotors Schaufeln (5) mit mindestens teilweise kurvenförmigem Verlauf in schraubenartiger Anordnung bis zu den Schrau­ benflügeln (3), in das das Innere des Zylindermantels reichend und daran derart befestigt sind, daß die Was­ serströmung bzw. Wassermenge vor dem Bereich der Schrauben­ flügel im wesentlichen in Richtung der Antriebsachse (1) und der Schraubenflügel (3) nach innen zwangsgeführt wird. The invention relates to a drive element for water vehicles, especially ships, on one of the Fixed hull protruding drive axle, screw aligned at a certain angle benwügeln (3) surrounded by a cylinder jacket (4) are. The drive element is characterized in that that on the drive axis (1) at a distance (L) from the Screw wings (3) in the direction of the drive motor Buckets (5) with at least partially curved Course in a screw arrangement up to the screw wing (3) into which the inside of the cylinder jacket reaching and attached to it in such a way that the what flow or amount of water in front of the area of the screws wing essentially in the direction of the drive axis (1) and the screw wing (3) is positively guided inwards.
