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.

Fuel filter passage for downward fuel flow direction

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.

Integral filter endcap, mold, and seal

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.

Filter element having potted gasket end cap assembly

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.

Filter interlock with tabs mating with a pedestal or a housing

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.

Filter element integrated seal profile

A filter pulsation dampening device has a replaceable filter element including a plurality of baffles disposed next to each other or a flexible valve that is disposed proximate a baffle.

Filter pulsation dampening device

A sensing system for detecting degradation of a machine fluid is disclosed. The sensing system may comprise a tag having electrical contacts. The tag may be configured to transmit a wireless signal when the electrical contacts are in electrical communication. The sensing system may further comprise a dissolvable element separating the electrical contacts and obstructing electrical communication between the electrical contacts. The dissolvable element may be configured to dissolve and allow electrical communication between the electrical contacts when an acid content of the machine fluid reaches a level indicative of the degradation of the machine fluid.

Sensing system for detecting machine fluid degradation

An air intake system may include an engine air cleaner having a dust valve. The intake system may be configured for arrangement on the engine. The dust valve may also be operable to open or close based on operating characteristics of the engine.
