摘要： A filter device includes a filter element (3), through which a fluid to be purified can flow at a determinable fluid operating pressure, and which can be accommodated in a housing (1). The fluid pressure prevailing at the respective filter element (3) may exhibit pressure increases or pressure peaks, which are damaging to the filter element (3), and in particular to its filter material (9), and which can be reduced and/or smoothened by a compensation device acting directly on the filter element (3) and having a flexible compensation element (29) that enables the volume of the fluid chamber of the housing (1) to be increased in accordance with a pressure peak or pressure increase. The flexible compensation element (29) is arranged between the outer side of the filter material (9) of the filter element (3) and the adjacent inner wall of the housing (1).

摘要： A filter device for filtering fluid particularly an aqueous urea solution, includes a filter housing (1), a filter element (11) and a compensating element (31) for compensating fluctuations in the pressure and/or volume of the fluid. At least one elastically-flexible membrane (31) serves as the compensating element. The membrane wall of of the membrane is held in a retaining part (35) and maintains a separation between the fluid and a compressible filling medium such as a working gas.

摘要： Disclosed is a filter device comprising at least one filter element (3), through which a fluid to be purified can flow with a determinable fluid operating pressure and which can be accommodated in a housing (1), wherein the fluid pressure prevailing at the respective filter element (3) may exhibit general pressure increases or pressure peaks which are damaging to the respective filter element (3), in particular to the filter material (9) thereof, and which can be reduced and/or smoothened by means of a compensation device which acts directly upon the respective filter element (3) and which has at least one flexible compensation element (29) that enables the volume of the fluid chamber of the housing (1) to be increased in accordance with a pressure peak or pressure increase, characterised in that the flexible compensation element (29) is arranged between the outer side of the filter material (9) of the filter element (3) and the adjacent inner wall of the housing (1).
