Claim Text:
1. A filter device, comprising: a filter element to filter a medium, the filter element having a dirty side and a clean side and a top axial end and opposing bottom axial end; a filter housing into which the filter element is received, the filter housing including a diverting part is arranged between the filter element and the outflow opening; wherein the diverting part extends axially upwardly away from the bottom axial end and terminates at a diverting part upper end positioned below the top axial end of the filter element; wherein the diverting part is embodied an annular blockade wall having an annular upper end face edge spaced radially outwardly from and extending circumferentially around the outflow channel member; wherein the overflow region is formed at the annular upper end face edge of the annular blockade wall; wherein, as the diverting part terminates below the top axial end of the filter element, open space starting at the annular upper end face edge and below the top axial end of the filter element forms the overflow region permitting flow to flow over the annular upper end face edge of the diverting part from the clean side of the filter element to the outflow opening; wherein the outflow opening is spaced radially inwardly away from a radial inner side of the diverting part; wherein the outflow channel member radially completely encloses the axially extending outflow passage from the bottom axial end of the filter element UP to the outflow opening, allowing fluid flow to enter the outflow passage only at the outflow opening and wherein the outflow opening is arranged at or near the annular upper end face edge and away from the bottom axial end of the filter element, wherein the upper edge of the outflow opening is arranged at the same axial height or slightly below the overflow region.
