The invention relates to a filter device for filtering fluid particularly in the form of an aqueous urea solution, comprising a filter housing (1) and a filter element (11) arranged therein, as well as a compensating element (31) for compensating fluctuations in the pressure and/or volume of the fluid, and characterised in that at least one elastically-flexible membrane (31) serves as the compensating element, the membrane wall of which is held in a retaining part (35) and maintains a separation between the fluid and a compressible filling medium such as a working gas. Eine Filtervorrichtung zum Filtern von Fluid, insbesondere in Form einer wässrigen Harnstofflösung, mit einem Filtergehäuse (1) und einem darin angeordneten Filterelement (11) sowie einem Ausgleichselement (31) zum Kompensieren von Druck- und/oder Volumenschwankungen des Fluids, ist dadurch gekennzeichnet, dass als Ausgleichselement mindestens eine elastisch nachgiebige Membran (31) eingesetzt ist, deren Membranwand in einem Halteteil (35) gehalten eine Trennung zwischen dem Fluid und einem kompressiblen Befüllmedium, wic einem Arbeitsgas, vornimmt.
A filter device for filtering fluid, particularly in the form of an aqueous urea solution, comprising a filter housing (1) and a filter element (11) arranged therein, as well as a compensating element (31) for compensating fluctuations in the pressure and/or volume of the fluid, characterized in that at least one elastically flexible diaphragm (31) serves as a compensating element, the diaphragm wall of which is held in a retaining part (35) and maintains a separation between the fluid and a compressible filling medium, such as a process gas.
