Abstract: A fluid filter assembly having a relief valve for visually indicating the life of a filter element. 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 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: By providing a fuel treating system with a strategically positioned sight-glass, it is possible to replace an fuel filter without either spilling large amounts of fuel all over or allowing for air bubbles, which can degrade the lubricating system's operation and cause siphoning. The sight-glass is positioned above the fuel inlet and outlet passages but below the filter. Thus, as soon as no fuel is seen in the sight-glass, a mechanic knows that the fuel filter has been substantially emptied of fuel yet the fuel inlet and outlet are still full.

Abstract: A method of visually indicating the number of chemicals and particulates processed by a filter element through which a fluid stream has flowed includes providing a volume meter to indicate when a volume of fluid has passed therethrough to indicate the ability of the filter element to reduce chemicals in the fluid stream, providing a flow rate meter to remove particulates, and positioning the volume meter upstream of the flow rate meter so that the volume meter delivers fluid to the flow rate meter which provides a visual indication as to whether the filter element is losing chemical reduction capacity or is clogged.

Abstract: A readily serviceable ancillary fluid filtration system has a fluid flow diverter with a quick-release fluid hose fitting (132). A manifold (200) is releasably securable to the cartridge filter (198) that includes a filter element (204) enclosed in a housing (202) covered by an end cap (208) having an inlet tube (210) and an outlet tube (212) that are matable with a push-in fitting (226) in at least one of the outlet and inlet of the manifold. A lever mechanism (230) pivotally mounted to the manifold pushes against the push-in fitting in response to a force applied to the lever by a user to separate the housing from the manifold.

Abstract: In a filter with fluid connections, an upper housing part (1) and a lower housing part (8) a flat filter blank (7) is sealingly clamped in like a sandwich between their circular and circumferential opening edges (6) and flange parts (11) in such a manner between the interconnected housing parts (1,8) that fluid can penetrate from one housing part (1) into the other housing part (8) only through the selectively permeable flat filter blank (7). The one housing part comprises threads (5) on the cylindrical outer edge of its opening edge facing the flat filter blank (7) and the connection of both housing parts (1,8) consists of a sprayed-on plastic ring (12) which holds the two housing parts (1,8) with flat filter blank (7) in a sealing and clamping position, completely fills up the threads (5) of the one housing part (1) and extends over the edge (11) of the other housing part (8) like a detachable union nut, so that a detachable housing connection is formed and the flat filter blank (7) can be removed from the filter housing for further testing.

Abstract: An in-line vacuum filter normally mounted between a vacuum pump and a vacuum packaging machine to block flow of process debris and sediment that collects at the outer surface of an outer screen of two concentric contiguous cylindrical screen with air flow inward through the two screens. The outer screen surface is viewable from the exterior of the vacuum filter through a transparent outer cylindrical enclosure so that a machine operator can easily see when it is time to disassemble and clean the filter of the sediment and debris buildup thereon. The transparent outer cylindrical enclosure and the two concentric cylindrical screens are held in the assembled vacuum filter between a bottom filter plate and a top filter plate all held together by one rod threaded on both ends with the top threaded into the top filter plate and the bottom extended through the bottom filter plate with a hex nut threaded on the bottom. "O" ring seals are mounted in annular grooves of both the bottom and top filter plates in position to seal space between groove edges and the inside of the transparent outer cylinder enclosure at opposite ends thereof when a vacuum is drawn in the filter.
