Abstract

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