Abstract: A suction filter device for filtering oil includes a filter housing having an oil inlet opening and an oil outlet opening, via which a filter housing interior can be fluidically connected to a suction line. An oil filter medium is arranged in the filter housing interior between the oil inlet opening and the oil outlet opening, so that, by means of negative pressure generated via the suction line within the filter housing interior in relation to an environment of the filter housing, an oil flow can be generated from the oil inlet opening through the oil filter medium and through the oil outlet opening. Further, an oil-permeable and air-impermeable air separation medium is included. The air separation medium is arranged upstream of the oil outlet opening when a vacuum is generated via the suction line within the filter housing interior in relation to an environment of the filter housing.

Abstract: Fluid filter arrangement for a motor vehicle drive train. The filter arrangement comprises a filter housing, which has a fluid inlet and a fluid outlet, allowing fluid to flow in one flow direction from the fluid inlet to the fluid outlet. A filter insert is arranged in the filter housing and divides an interior of the filter housing into an inlet region connected to the fluid inlet and an outlet region connected to the fluid outlet. The filter insert has a filter medium for filtering fluid. The filter insert has a perforated plate having a plurality of holes. The holes are arranged ahead of the filter medium in the flow direction. The size of at least some of the holes is adapted so that fluid impinges upon the filter medium at an increased flow velocity.
