Abstract: A filter device is disclosed comprising a filter which is used to clean a fluid flow of particulate contamination in a specifiable flow direction, having a fluid inlet for supplying an unfiltered medium flow, a fluid outlet for removing a filtrate flow, and a discharge opening for discharging a backflushing fluid produced while backflushing the filter against the specifiable flow direction using a backflushing device, wherein as the particulate contamination being cleaned out of the fluid flow by the filter increases, the differential pressure between the fluid inlet and the fluid outlet increases, characterised in that a valve device is arranged downstream of the discharge opening, viewed in the fluid flow direction, said valve device regulating the discharge rate of backflushing fluid as a function of the differential pressure.

Abstract: A filter apparatus (10) has a plurality of filter elements (20) in a filter housing (12) having a filter inlet (50) for a fluid to be filtered and a filter outlet (52) for the filtered fluid. A pressure control device (42) has at least one control plate (58) located inside a connection chamber (14). The control plate laterally passes over individual upper element openings (54) of the filter element to be backwashed (20), in a predefinable sequence, covering the opening to an increasing degree and then exposing the opening again. A discharge opening (46) of the backwash device (44) is, at least in part, fluidically connected to a lower element opening (56) of the filter element (20) to be backwashed, as the pressure control device (42) moves towards the upper element opening (54).

Abstract: A filter device for fluids includes a housing (1) accommodating a filter element (5). The housing has an inlet (47) for the supply of fluid to be purified to a non-filtrate chamber (49) of the housing (1) and has an outlet 42 for the filtrate. The non-filtrate chamber is separated from a filtrate chamber (46) of the housing (1) by the filter medium (33). A magnetic field-generator unit (57) is arranged inside the non-filtrate chamber (49). An adhering surface a sleeve or casing (51) attracts ferromagnetic particles by a magnetic force effect. In the non-filtrate chamber (49), the sleeve (51) extends outside of the respective filter element (5) parallel to the inlet (47) and transversely to the outlet (42). The non-filtrate chamber (49) at least partially encompasses the outlet (42) at the point of transition to the filtrate chamber (46).
