    Abstract: A filter device having a filter housing (1) with a fluid inlet (13) for raw fluid and with a fluid outlet (3) for filtrate and with at least one one-piece or multi-piece filter insert (5, 7) which is received in the filter housing (1) and can be cleaned using at least one backflushing member (21) in counter-current to the filtration direction, which member can, by means of a fluid-guiding driveshaft (23) of a rotary drive (35), be moved along the inner side (19) of the respective filter insert (5, 7) and has, at its end adjacent to this inner side (19), a gap-shaped passage opening (39) that runs parallel to the axis of rotation of the driveshaft (23) and discharges into a flow space (41; 57; 67) fluidically connected to the driveshaft (23), which space at least partially continuously nar¬rows in the direction of the driveshaft (23) in a first plane in which the passage opening (39) lies, is characterized in that, in another second plane transverse to the first plane, the flow space (41; 57; 67) at least partially continuously widens proceeding from the passage opening (39) in the direction of the driveshaft (23).

    Abstract: A filter device, comprising a filter housing (1) having a fluid inlet (8) for unfiltered matter and having a fluid outlet (9) for filtrate and having at least one one-piece or multi-part filter insert (05, 17) held in the filter housing (1), which filter insert (15, 17) can be cleaned using a backwash device (25) having at least one backwash element (31) in counter flow to the direction of filtration, which backwash element can be moved along the inside of the relevant filter insert (15, 17) by means of a fluid-conveying drive shaft (29) of a rotary drive (69, 71), wherein the individual backwash element (31) has, at the end adjacent to this inside, at least one gap-shaped passage opening, which extends in parallel to the axis of rotation of the drive shaft (29) and which opens into a flow chamber connected to the drive shaft (29) in a fluid-conveying manner, is characterized in that at least one further backwash device (27) having at least one further backwash element (31) is present, in that the fluid-conveying drive shaft (29) is divided into chambers (73, 75) separated from each other, and in that in each case one backwash element (31) of one backwash device (25) is connected to one of the chambers (73, 75) and the other backwash element (31) of the other backwash device (27) is connected to another chamber (73, 75).
