Abstract:
1. A filtering device comprising: a filter housing in the form of a support pipe defining within said support pipe a selected filter element course geometry; a filter element comprising a flexible filter hose of yielding filter material extending axially in said support pipe along said course, said flexibility enabling said filter element to follow and conform to said selected course geometry; an adsorber unit arranged in a flow path through the filtering device of a fluid to be purified in the filtering device; wherein said filter hose has a filter wall that separates radially an unfiltered side from a filtered side of the filtering device; wherein between an outer side of said filter wall of said filter hose and an inner wall of said support pipe an annular chamber for flow of the fluid to be purified is formed; wherein said adsorber unit is arranged in or on said support pipe; wherein said filter element is adapted to conform to a variety of course geometries by way of its flexibility, and wherein the filter housing is in fluid communication with an air intake in an internal combustion engine.
