Abstract

A filter device, especially intended for incorporation into a fluid reservoir tank, has at least one, preferably exchangeable, filter element (18) having element material (20) through which a fluid can flow from the inside outward, viewed in radial direction, and encompassed by a support tube (36) with passage orifices. The support tube is surrounded with a fluid flow space defined by a housing wall of a housing and has a plurality of passage sites. At least some of the passage orifices in the support tube (36) of the filter element (18) have a flow-directing device (80) that impart a flow direction other than the radial flow direction to the fluid.
