Abstract

Fluid-Rotationsmaschine (1) mit einem Gehäuse (2), einer aus dem Gehäuse (2) geführten Welle (3), die um eine Achse (4) drehbar ist und Teil eines Bewegungsstranges bildet und einer Sensoranordnung (10), die einen Geber (12) und einen Empfänger (15) aufweist.Fluid rotary machine (1) comprising a housing (2), a guided from the housing (2) shaft (3) which is rotatable about an axis (4) and forms part of a moving train and a sensor arrangement (10), the encoder (12) and a receiver (15).

Im Bewegungsstrang ist ein Kanal (21) vorgesehen und der Geber (12) ist mit einem ein Drehmoment übertragendes Übertragungselement (19) verbunden, das durch den Kanal zu einem Abschnitt (21) geführt ist, der vom Geber (12) weiter entfernt ist als ein geberseitiges Ende des Bewegungsstranges.

Figure imgaf001
In the motion strand, a channel (21) is provided and the encoder (12) is connected to a torque transmitting transmission element (19), which is guided through the channel to a portion (21) which is further away from the encoder (12) than a geberseitiges end of the movement strand.
