Filter device
Document Type and Number:
Japanese Patent JP6158790
Kind Code:
B2
Abstract:
A filtering apparatus has filtering elements (11) in a filter housing (1), a filter inlet (7) and a filter outlet (9). During filtration, one of the filter elements (11) can be back-flushed by a back-flushing device (45, 49), having a pressure control device (19). The pressure control device has a hydraulic accumulator (19), with a fluid chamber (47) fillable during filtration with clean fluid and connectable for back-flushing via a back-flushing guide (45) to the clean side (29) of the filtering element (11) to be cleaned. For back-flushing, a further fluid chamber (48) of the hydraulic accumulator (19) is subjected to gas pressure. By resultant movement of a separator (59) of the hydraulic accumulator (19), the filling amount of the clean fluid is dispensed for the back-flushing.
