Filter element for filtering e.g. fuel with contaminations, has fixing unit provided in form of fixing bodies protruding from surface element, where bodies are stably and partially engaged in folding interstices formed between rear parts

摘要

The element has a multilayer formed filtering medium (3) asteroidally folded and forming a hollow cylinder, which surrounds a fluid-transmissive support tube. A fixing unit is provided at a partially surrounding surface element and comprises a knob (5). The fixing unit is co-acted with the filtering medium for stabilization of geometry of foldings. The fixing unit is provided in a form of fixing bodies protruding from the surface element that comprises a plastic sheet (1). The bodies are stably and partially engaged in folding interstices (9), which are formed between folding rear parts.
