Abstract: A lubricant filter assembly includes a filter cartridge including a cylindrical filter medium and a top cap. The cylindrical filter medium extends circumferentially about a longitudinal axis of the filter assembly. The cylindrical filter medium extends between and to a first filter end and a second filter end along the longitudinal axis. The cylindrical filter medium forms a filter passage extending from the first filter end to the second filter end. The top cap is disposed on the cylindrical filter medium at the first filter end. The top cap includes an inner diameter ring, an outer diameter ring, and an interior packing. The inner diameter ring forms a first filter outlet passage coincident with the filter passage. The inner diameter ring includes a first set of locking tabs. The outer diameter ring radially circumscribes the cylindrical filter medium.

Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore and a valve body received at least in sections thereof in the valve bore. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to a valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and transferred from the open state into the closed state. The valve body, upon transfer of the water drainage device from the closed state into the open state, moves linearly along the longitudinal axis of the valve bore and away from the valve seat along or at a slant to a direction of gravity in downward direction.
