Abstract
A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.
Claims18
A fluid filter comprising:
- a filter media having a center axis;
- a first end plate comprising a first path centered on the center axis and a second path extending at a non-zero angle from the first path;
- a second end plate;
- a first seal disposed along the first path and along a first side of the second path;
- a bypass seal disposed along a second side of the second path substantially opposite the first seal, the bypass seal positioned on a first surface of the first end plate;
- wherein the filter media is disposed between the first end plate and the second end plate, and wherein the first end plate is configured such that the bypass seal is disposed above the filter media and is separated from the filter media by the first end plate.

- and
- a fluid filter comprising:
- a filter media having a center axis;
- a first end plate comprising a first path centered on the center axis;
- a second end plate;
- and
- a bypass seal disposed along the first path, the bypass seal positioned on a first surface of the first end plate;
- wherein the filter media is disposed between the first end plate and the second end plate;

A fluid filter comprising:
- a filter media;
- a first end plate comprising:
- a projection extending away from the filter media;
- a first path formed in the projection, and
- a second path in fluid communication with the first path, the second path formed in the projection;
- a second end plate, the second end plate being a closed end plate;
- a first seal disposed along the first path and along a first side of the second path;
- and
- a bypass seal disposed along a second side of the second first path substantially opposite the first seal, the bypass seal positioned on the first end plate;
- and
- wherein the filter media is disposed between the first end plate and the second end plate;
- and
- wherein the first end plate is configured such that the bypass seal is disposed above the filter media and is separated from the filter media by the first end plate.

A system comprising:
- a filter head comprising a bypass flow outlet;
- and
- a fluid filter comprising:
- a filter media having a center axis;
- a first end plate comprising a first path centered on the center axis;

- and
- an internal seal located on the first end plate, the internal seal configured to seal against the filter head and separate an unfiltered fluid from a filtered fluid;
- wherein:
- the fluid filter is configured to be engaged with the filter head;
- the bypass seal is configured to block fluid flow from the first path to the bypass flow outlet when the fluid filter is engaged with the filter head;
- the first end plate comprises a second path in fluid communication with the first path;
- and
- the bypass seal is configured to cause fluid to flow from the first path to the second path;
- and
- wherein the second path extends between the bypass seal and the internal seal.
