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.
Claims8
A canister filter system comprising:
- a filter element that includes at least partially a cylindrical configuration and that defines a longitudinal axis, and a radial direction, the filter element comprising:
- an annular filter media defining a central passage;
- a center tube that is disposed in the central passage of the annular filter media that defines a central reservoir, and the annular filter media surrounds the center tube and the central reservoir;
- a central fluid supply tube that is disposed in the central reservoir of the center tube, defining a supply passage;
- a top open end joined to the center tube disposed along the longitudinal axis, the top open end including an opening allowing fluid to flow from the central reservoir to the outside of the filter element;
- a bottom open end joined to the center tube opposite the top open end disposed along the longitudinal axis:
- a canister that includes a top closed end, and a bottom open end disposed along the longitudinal axis;
- a pedestal including
- an at least partially annular body;
- 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;
- and
- a flow aperture that extends through the annular wall;
- and
- wherein the pedestal is attached to the top closed end of the canister;
- and
- an integrated seal member that is attached to the bottom open end of the filter element, the integrated seal member including a radially inner mounting portion, a radially outer seal portion, and an apertured connecting portion that extends from the radially inner mounting portion to the radially outer seal portion.
