Abstract: Oil sump arrangements, such as transmission oil sumps and lubricating oil sumps used with the drive train of automotive vehicles are divided into an upper chamber and a lower chamber with a filter media disposed between the upper chamber and the lower chamber. The oil being circulated to a transmission or an engine pools in the lower chamber and is sucked by a suction tube out of the lower chamber for recirculation. In order to prevent the oil from pooling or accumulating under centrifugal force away from the suction tube so that air is ingested by the suction tube and the transmission or engine momentarily starved for oil, a plurality of baffle plates are placed in the lower chamber and extended parallel to the longitudinal axis of the vehicle which is the normal direction of motion of the vehicle. The baffle plates obstruct movement of the oil away from the suction tube inlet.

Abstract: An oil filter unit comprising a housing (4) and a filter element (14) accommodated therein is fitted to an engine (1) via a bracket (3) having a cylindrical holder (5). The housing (4) is secured to the holder (5) by screwing a male screw (19) on its outer circumference to a female screw (17) formed in the inner circumference of the holder (5). A first cut-out (24) is formed across the female screw (17) and a second cut-out (23) is formed across the male screw (19). When these cut-outs (24, 23) meet together, they form a drain passage which drains the oil in the housing (4) to outside. With this construction, the oil in the housing is drained via a predetermined path and prevented from scattering around, when the filter unit is removed from the engine (1).
