Abstract
In a particularly noise-free and vibration-free operating precoated filter for filtering for example cooling lubricating means, a filter candle 12 surrounding a riser channel 16 is mounted by means of a riser tube 15 in a separating plate 5 in an axially moveable manner. A filter cake adhering to the outside of the filter candle 12 is loosened in such a manner that for example a disk-shaped rotary body 40 comprises a shoulder 42 between the track end 43 and the track start 44 along its track 41. As soon as a head end piece 20 connected to the riser tube 15 and moveable in an axial manner against the force of a spring 21 is released from the rotating track end 41, the stored force of the spring 21 accelerates the filter candle 12, so that the filter cake adhering to the filter candles is loosened by the acceleration of the filter candle 12 and the impact pulse when a dampening ring arranged between the filter candle 12 and the separating plate 5 abuts the separating plate.
