The oil filter has a valve (1), a valve seat (8) and a valve closing member (9). A spring element (11) is provided, which is subjected against the valve seat. The valve closing member is lifted up by excess oil pressure in an opening direction of the valve seat. The spring element is made up of composite material, particularly thermoplastic and is strengthened with continuous manufactured fibers. The spring element is made from a plate. The thermoplastic is polyamide and the fibers are glass or carbon fibers. Bei einem Ölfilter mit mindestens einem Ventil (1) umfasst das Ventil einen Ventilsitz (8) und ein von einem Federelement (11) gegen den Ventilsitz (8) beaufschlagtes Ventilschließglied (9). Das Ventilschließglied ist bei Überschreiten eines vorgegebenen Öldrucks in Öffnungsrichtung (14) vom Ventilsitz (8) abhebbar. Um das Ventil (1) aus nichtmetallischen Werkstoffen zu konstruieren, besteht das Federelement (11) aus einem Verbundwerkstoff, und zwar aus einem The rmoplasten, der mit kontinuierlich hergestellten Fasern verstärkt ist.
