The present invention provides a suction oil filter device for an engine or a transmission that has an oil inlet and an oil outlet on the filter housing, a suction oil pump connectable to the oil outlet, using which a partial vacuum may be generated between oil inlet and oil outlet, a fine filter medium and an ultrafine filter medium, which are situated between the oil inlet and the oil outlet. The fine filter medium is attached to the oil inlet or to the oil outlet, and the ultrafine filter medium is situated before the fine filter medium in the flow direction and in a secondary flow area of the filter housing. A high filtration performance may thus be achieved at low production outlay.

The invention relates to an oil filter apparatus comprising an oil inlet and an oil outlet, with a suction oil pump being connectable to the oil outlet with which a negative pressure can be produced between the oil inlet (and the oil outlet, a coarse filter medium and a fine filter medium which is arranged between the oil inlet and the oil outlet, with the oil filter apparatus being capable of allowing a volume share of the oil to pass permanently through the coarse filter medium irrespective of the viscosity of an oil passing through the oil inlet and of allowing at the same time the remaining volume share of the oil to pass through the fine filter medium. The entire oil volume flow can thus be purified in a short period of time with high efficiency, and no additional space is required outside of the transmission or engine, a light and cost-effective configuration is achieved, and the oil filter apparatus can be used in different vehicle models or types of engines without any change and thus without any reduction in the variety of variants.
