FILTER CARTRIDGE FOR TRANSLATIONAL INSERTION AND ROTATIONAL ENGAGEMENT OF A MANIFOLD
First Claim
1. A filter cartridge comprising:
- a cartridge body having a filter media disposed therein and a longitudinal axis down the center of the filter cartridge;
a stem extending longitudinally from the cartridge body, the stem having an inlet opening an outlet opening, and a stem face on a distal end;
the stem face comprising an aperture having a valve engagement member comprising a first valve driving surface and a second valve driving surface located in the aperture, the aperture extending through the longitudinal axis;
at least one lug attached to either the filter body or the stem and having a leading engagement edge; and
wherein the first valve driving surface faces a first rotational direction about the longitudinal axis and the second valve driving surface faces a second rotational direction about the longitudinal axis;
the first valve driving surface and the second valve driving surface both extend longitudinally and are separated by a first timing radial arc along a perimeter of the stem.

Abstract
Described are filter cartridges comprising: a cartridge body and a filter media; a stem extending from the cartridge body, the stem having an inlet opening, an outlet opening, and a stem face that comprises a first valve driving surface and a second valve driving surface; and at least one lug attached to either the filter body or the stem having a leading engagement edge. The filter cartridges are suitable for translational insertion and rotational engagement of a manifold, wherein upon translation insertion, a valve engagement member of the filter cartridge engages a portion of a valve body of a manifold valve; during a first stage rotation, one or more retaining members of the filter cartridge engage a manifold cam of a manifold; and during a second stage rotation, the valve engagement member imparts rotational movement to the valve body. Systems and methods incorporating the filter cartridges are disclosed.
