Abstract
A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing.
Claims27
A fluid filter device comprising:
- a housing having a filter cartridge disposed therein, the filter cartridge containing a filter media;
- and
- a flow attachment member configured to communicate fluid to be filtered to the filter media, and configured to communicate fluid filtered by the filter media out of the fluid filter, the flow attachment member includes
- a structure configured to localize fluid flow both into and out of the fluid filter, and
- a seal structure disposed about an outer surface of the structure configured to localize fluid flow, the seal structure configured to substantially prevent or confine leakage from the structure configured to localize fluid.
A flow attachment as an adapter for a fluid filter comprising:
- a stem configured to communicate fluid to be filtered to the fluid filter, and configured to communicate fluid out of the fluid filter, the stem includes
- a structure configured to localize fluid flow both into and out of the flow attachment, and
- a seal structure disposed about an outer surface of the structure configured to localize fluid flow, the seal structure configured to substantially prevent or confine leakage from the structure configured to localize fluid.
