Abstract

A flow cap may include an outer ring, an inner ring, an inlet portion, and an outlet portion. The inlet portion may include first portions of the outer and inner rings, and a plurality of arms extending between the first portions of the outer and inner rings, wherein the arms at least partially define an inlet aperture configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element. The outlet portion may include second portions of the outer and inner rings, and a plate including an outlet aperture providing flow communication between an outlet port of the filter base and an exterior portion of the filter element. The outlet portion may also include a wall, wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

Dependent claims

A flow cap configured to provide flow communication with an interior portion of a filter element and an exterior portion of the filter element, the flow cap comprising:

an outer ring;
an inner ring associated with the outer ring;
an inlet portion configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element, the inlet portion including:
a first portion of the outer ring,
a first portion of the inner ring, and
a plurality of arms extending between the first portion of the outer ring and the first portion of the inner ring,
wherein the arms at least partially define an inlet aperture configured to provide flow communication between the inlet port of the filter base and the interior portion of the filter element;
and
an outlet portion configured to provide flow communication between an outlet port of the filter base and an exterior portion of the filter element, the outlet portion including:
a second portion of the outer ring,
a second portion of the inner ring,
a plate associated with the inner ring, the plate including an outlet aperture providing flow communication between the outlet port of the filter base and the exterior portion of the filter element, and
a wall extending between the second portion of the outer ring and the second portion of the inner ring,
wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

11 more elements

A flow cap configured to provide flow communication with an interior portion of a filter element and an exterior portion of the filter element, the flow cap comprising:

an inlet section;
an outlet section associated with the inlet section;
an inlet portion defined by the inlet section and configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element, the inlet portion including an inlet aperture configured to provide flow communication between the inlet port of the filter base and the interior portion of the filter element;
and
an outlet portion defined by the outlet section and configured to provide flow communication between an outlet port of the filter base and an exterior portion of the filter element, the outlet portion including an outlet aperture providing flow communication between the outlet port of the filter base and the exterior portion of the filter element,
wherein the inlet portion of the flow cap is configured to provide flow communication between the inlet port of a filter base and the interior portion of the filter element in a direction substantially toward a central portion of the flow cap,
wherein the outlet portion of the flow cap is configured to provide flow communication between the outlet port of the filter base and the exterior portion of the filter element in a directional substantially toward the central portion of the flow cap,
wherein the flow cap has a substantially circular cross-section perpendicular to a longitudinal axis of the flow cap, and
further including an outer ring and an inner ring associated with the outer ring, wherein the inlet portion of the flow cap includes a first portion of the outer ring and a first portion of the inner ring, and wherein the outlet portion of the flow cap includes a second portion of the outer ring and a second portion of the inner ring.
