    Abstract: A fluid filter assembly having a relief valve for visually indicating [the life of] when a filter element may be replaced. The fluid filter assembly of the present invention provides a vertical, transparent housing having a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream of said housing. A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. In [the preferred] a first embodiment, a [frusto-conical] divider is connected to the top of the filter element and extends downward adjacent a bottom portion of the filter element wherein the fluid from the inlet rises between the filter element and the inside of the divider and between the outside of the divider and an inside surface of the housing. A relief valve is provided in the top of the filter element and is in communication with the unfiltered and filtered side of the filter element. The relief valve opens at a predetermined pressure level across the filter element thereby raising the fluid level and providing a practical [visual] indicator that the filter element may be replaced [needs replacement].

A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. In the preferred embodiment, a frusto-conical divider is connected to the top of the filter element and extends downward adjacent a bottom portion of the filter element wherein the fluid from the inlet rises between the filter element and the inside of the divider and between the outside of the divider and an inside surface of the housing. A relief valve is provided in the top of the filter element and is in communication with the unfiltered and filtered side of the filter element. The relief valve opens at a predetermined pressure level across the filter element thereby raising the fluid level and providing a visual indicator that the filter element needs replacement.

    Abstract: A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

    Abstract: A lubricant filter assembly includes a filter cartridge including a cylindrical filter medium and a top cap. The cylindrical filter medium extends circumferentially about a longitudinal axis of the filter assembly. The cylindrical filter medium extends between and to a first filter end and a second filter end along the longitudinal axis. The cylindrical filter medium forms a filter passage extending from the first filter end to the second filter end. The top cap is disposed on the cylindrical filter medium at the first filter end. The top cap includes an inner diameter ring, an outer diameter ring, and an interior packing. The inner diameter ring forms a first filter outlet passage coincident with the filter passage. The inner diameter ring includes a first set of locking tabs. The outer diameter ring radially circumscribes the cylindrical filter medium.
