A filter has a filter center tube that includes a plurality of layers of solidified material including a first layer with a first undulating strip of solidified material extending in a first predetermined direction, and a second layer with a second undulating strip of solidified material extending in a second predetermined direction. The first layer is in contact with the second layer and the first predetermined direction is not parallel with the second predetermined direction, forming a plurality of pores therebetween.

A method of assembling a canister filter system includes inserting a first filter component into a second filter component, and continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

Filter element locking mechanism

A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

An anti-prefill device may be disposed at a radially central portion of an endcap mounted on one axial end of an annular filter medium in a filter system. The anti-prefill device includes a first, annular, fluid receiving portion including an externally threaded engagement surface configured to be threadingly engaged with a central, internally threaded boss of a filter base of the filter system at the axial end of the annular filter medium, the first, annular, fluid receiving portion defining an annular concave recess open upwards toward the filter base of the filter system, and a second, annular, fluid blocking portion configured as a cylindrical cap overlapping a radially central tubular portion of the first, annular, fluid receiving portion that projects upwards toward the filter base from a radially inner extent of the radially central portion of the endcap, the second, annular fluid blocking portion being oriented with a concave recess of the cylindrical cap open downwards toward the first, annular, fluid receiving portion.

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

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.

Top and bottom loaded filter and locking mechanism

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.

Locking feature for a filter

The present disclosure relates to a filter element for use in a fluid filter system is disclosed herein. The filter element comprises a filter medium having a longitudinal axis between a first end and a second end, and an end cap assembly attached to the first end of the filter medium. The end cap assembly includes a first end cap aligned with the longitudinal axis and proximate to the first end of the filter medium; a first member concentric with and disposed radially apart from the first end cap and the filter medium and axially between the first end cap and the second end of the filter medium; and a plurality of arms connecting the first end cap with the first member, each arm configured to align the filter element with respect to the container and base plate by absorbing alignment discrepancies between at least the base plate and container.

A filter module for filtering fuel in an engine system includes a primary filter, a secondary filter, and a module housing. A drain valve is movable between a closed position blocking a drain port in the module housing, and an open position. A service valve assembly is positioned at least partially within a cross passage in the module housing and adjustable from a closed configuration blocking a primary-side fuel passage from a secondary-side fuel passage in the module housing, to an open configuration, to drain fluids from the filter module by way of the single drain port.

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.

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and an apertured connecting portion that extends radially outwardly from the mounting portion to the sealing portion.
