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