<p>The disadvantages of known type of dispensing devices lies in the fact that the dosage of grease is not controlled or cannot even be stopped. According to the claimed arrangement these disadvantages are circumvented by the following measures: Between the grease dispensing device (4) and the bearing of the shaft (1) an electrically controlled valve-mechanism (9) is applied by means of which grease can be supplied to said bearing. This valve-mechanism (9) is (electrically) connected to a circuit provided with a coil system (10). The coil comprises an U-shaped part (12) between which legs a ring (11) with magnets fixed to the shaft (1) can rotate. Due to this arrangement the valve-mechanism (9), thus the supply of grease, is controlled by rotation of the said shaft (1).</p> |
