Abstract

In one example, a core cover includes an inner wall that defines a fluid passageway configured to communicate with an interior of a filter core when the core cover is engaged with the filter core. As well, the core cover includes an outer wall spaced apart from the inner wall, and a complementary structure located on the outer wall and configured to engage a corresponding complementary structure of a filter core. Finally, the core cover includes one or more indicia that indicate a flow rate, or range of flow rates, associated with the core cover.

First claim

What is claimed is:

1. A core cover, comprising:
an annular end face;
an annular inner wall having a first inner end and a second inner end, the first inner end coupled to the annular end face and the second inner end cantilevered from the annular end face; and
an annular outer wall having a first outer end and a second outer end, the first outer end coupled to the annular end face and the second outer end cantilevered from the annular end face;
wherein the core cover is configured to be engaged with a filter core to define a fluid passageway to communicate with an interior of the filter core.

2. The core cover of claim 1 , wherein the core cover is a unitary, single-piece construction.

3. The core cover of claim 1 , further comprising indicia to indicate a flow rate or range of flow rates associated with the core cover.

4. The core cover of claim 1 , further comprising a complementary structure configured to engage a corresponding complementary structure of the filter core to attach the core cover to the filter core.

5. The core cover of claim 4 , wherein the complementary structure is an annular ring radially extending from the outer wall.

6. The core cover of claim 1 , wherein the outer wall is configured to flex in a radial direction upon engaging the core cover with the filter core.
