A stirring device (1) comprises a holding casing and an inner stirring element. The inner stirring element comprises an impeller (11) provided with recesses for housing magnetic bodies (12). On the outer surface of a portion of the device (1) is housed a gear wheel (13) in turn provided with recesses for housing magnets (14). As the device (1) operates, the impeller (11) is magnetically coupled to the gear wheel (13), the rotary movement of which will drive the stirring element. The device provides the advantage that it is not necessary to provide sealing elements on the body of the vessel, in particular at the driving means for driving said stirring element. <IMAGE> |
