Abstract: A filter for a fluid system includes a filter housing, and a filter medium within the filter housing. A filter cap component is coupled to the filter housing and includes a fluid distribution wall having therein a plurality of fluid openings. The filter further includes a seal having an annular central body and a valving skirt contacting an outgoing wall surface of the filter cap component at an anti-drain back sealing location. The valving skirt is deformable away from the outgoing wall surface to permit fluid flow through the fluid distribution wall, and alternately seals against the fluid distribution wall to prevent drain back.

Abstract: A filter element includes a bottom open end joined to a center tube opposite the top open end. The bottom open end defines a radially outer surface and a radially inner surface that is in communication with the central reservoir of the filter element. A locking feature is disposed proximate to the bottom open end. The locking feature includes an entrance slot that is disposed on the radially inner surface of the center tube extending axially from the bottom open end.

Abstract: A filter element includes a bottom open end joined to a center tube opposite the top open end. The bottom open end defines a radially outer surface and a radially inner surface that is in communication with the central reservoir of the filter element. A first locking feature is disposed proximate to the bottom open end. The locking feature includes an entrance slot that is disposed on the radially inner surface of the center tube extending axially from the bottom open end. A similar or identical second locking feature is disposed proximate to the top open end.

Abstract: A pedestal for use with a canister filter system and a filter element for positioning and retaining the filter element in the canister filter system includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. Also, the pedestal includes an annular wall that terminates at a bottom free end, and that defines a slot that extends axially upwardly and circumferentially from the bottom free end. A flow aperture extends through the annular wall that is disposed axially above the slot.
