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: A line strainer for screening fluid flow in a small diameter conduit is constructed with an integral housing of clear or transparent thermoplastic polymer. A fluid flow channel through the housing center is terminated at opposite ends by sonically welded end fittings. Internally of the housing, a screen chamber is separated from a flow meter chamber by a screen support hub with flow diversion passages. The screen chamber confines a conically formed screen mesh for passing substantially all flow through the housing. The flow meter chamber has conically tapered walls that support radial fins projecting from the walls inwardly to a cylindrical void that confines the metering ball to displacement along the housing axis. A spring bearing against the metering ball resiliently biases the ball toward the flow restriction passage and against the fluid flow direction. The spring bias and conically tapered meter walls cooperate with the flow stream and metering ball to stabilize at a position along the housing axis that is proportional to the flow rate through the screen. As the screen mesh fills to increase flow stream resistance, the metering ball approaches the flow restriction passage signaling a reduced flow rate. The degree of plugging or filling of the screen mesh is therefore indicated by the relative position of the metering ball for a substantially constant pressure source. Additionally, pump performance or system blockage could also be detected by the ball position in the flow meter chamber.

Abstract: A readily serviceable ancillary fluid filtration system has a fluid flow diverter with a quick-release fluid hose fitting (132). The quick-release fitting attaches to and receives fluid flowing from a manually actuatable diverter body (130) that is attachable to a faucet waterspout (104). The fitting carries a pivotally mounted lever arm (168) that functions as a manually actuatable push tab-release mechanism. A user squeezes the free end (182) of the lever arm to release a hooked end (166) thereof from a flange (158) extending from the body and either inserts tubes (174, 176) into or withdraws the tubes from the diverter conduits (152, 154).

Abstract: A snap-together, all-plastic filter assembly for filtering fluids includes a generally cylindrical injection molded plastic outer shell which has a closed base and an open opposite end and which defines a hollow interior which receives a filtering element and an integral injection molded plastic endplate/centertube member. The outer shell is injection molded with a pair of concentric, generally cylindrical, inner annular walls which are integral with the closed based and extend part way toward the open end of the outer shell. The filtering element which has a hollow interior fits down within the outermost of the two concentric annular walls and the centertube of the endplate/centertube member extends through the center of the filtering element and snaps in place by means of snap-fit projections which snap into snap-fit pockets disposed within the inner most of the two concentric annular walls. The filter assembly is designed as a spin-on filter and is threadedly engaged and positioned onto a mounting base thereby completing the fluid flow path. In related embodiments the filtering element is preassembled to the endplate/centertube member as a replaceable cartridge.

Abstract: A fuel filter assembly that provides a constant level of least restricted fuel flow through the fuel filter assembly during the useful life of the filter media by utilizing the least possible amount of filter media to provide the least possible pressure differential over the filter media while also providing a constant level of fuel additive by exposing an amount proportional to the filter media required for the least possible restricted fuel flow. The fuel filter assembly utilizes a vertically upward housing that houses a filter media and a fuel additive. The fuel level slowly rises in the housing as the filter media becomes obstructed with contaminants and as the fuel additive dissolves over the life of the filter media. The top portion of the housing is made of a transparent material so that the level of fuel level may be easily determined, thereby allowing for an accurate and simple assessment of the useful life of the filter media and the fuel additive. The housing also provides a multi-purpose aperture provided in the top of the housing to provide for removal and/or replacement of the fuel additive and venting and priming of the housing. The filter media and fuel additive are entirely fabricated from combustible materials so that both may be easily discarded without cost and environmental concerns.

Abstract: This device provides a visual media for instantly determining the then-filtering capacity of the filter elements or media in a water filtration apparatus. The system includes a bypass channel or chamber disposed in an upstanding position and having freely and slidably mounted therein a movable indicator element having a specific gravity somewhat above that of water. This bypass channel or chamber is connected at its lower end with the liquid or water in a filter tank, which is subjected to pressure imposed by a recirculating pump, and the upper end of said bypass is in communication with the liquid pressure passing through from the collection manifold of the filter apparatus to the return line to the pool or other main repository for the water. When the filter media is in a clean or new condition, the pressure from the upper connection of the bypass will be slightly less than from the tank or bottom connection, and as the filter media becomes impregnated or contaminated or clogged, the collection manifold pressure due to the decline of water flow decreases further while simultaneously the pressure at the lower end of the bypass from the filter tank increases. This differential pressure is responsible for an upwardly escape velocity in the bypass chamber, causing the indicator element proper to rise in a direct relationship to the degree of contamination or clogging.
