Abstract
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.
