    摘要： A fluid filter having a filter canister, a fluid inlet, a fluid outlet, filter media, and a pressure sensitive valve assembly is described. The pressure sensitive valve assembly comprises an orifice surround, a pressure relief spring, and a valve plug comprising a valve head and first and second retention legs. The first and second retention legs of the valve plug are spaced apart from one another, extend from a leg base positioned at the sealing side of the valve head to a distal end of the retention leg, and comprise respective seating regions, tapered transition regions, and clearance regions. Each of the respective seating regions comprises a spring engaging hook structurally configured to receive a seating portion of the pressure relief spring. The pressure relief spring is compressed between the orifice surround and the spring engaging hooks to bias the pressure sensitive valve assembly towards the closed state.

    摘要： A safety screen assembly includes a shroud sleeve with an upstream end that defines a flow inlet. A spring seat is disposed downstream from the shroud sleeve and includes a flow outlet. A screen spool is operatively disposed between the flow inlet and the flow outlet and includes a tubular body with an inner passage, a screen disposed within the inner passage, and a plurality of bypass passages formed in the tubular body. The tubular body is in sliding engagement with the shroud sleeve in both a first position and a second position, the shroud sleeve closing the plurality of bypass passages from fluid flow when the tubular body is in the first position, and the plurality of bypass passages being open to fluid flow when the tubular body is in the second position. A spring biases the tubular body of the screen spool toward the first position.

    摘要： A fuel supply system includes a fuel supply line, a fuel filter, a filter bypass line, a first differential pressure sensor, a second differential pressure sensor, and a filter bypass valve. The fuel filter is disposed in series in the fuel supply line to remove particulate from the fuel. The filter bypass line has a fuel inlet upstream of the fuel filter, and an outlet that is downstream of the fuel filter. The first differential pressure sensor continuously senses differential pressure across the fuel filter, and the second differential pressure sensor selectively senses differential pressure across the fuel filter. The filter bypass valve is movable between a first non-bypassing position and a second bypassing position and controls whether only the first differential pressure sensor or both the first and second differential pressure sensors sense the differential pressure across the fuel filter.

    摘要： An engine oil filter is provided that comprises a transparent sidewall for inspecting the oil content within the oil filter interior. The oil filter comprises an oil filter housing with a filter element, a center tube, a base plate, and a biasing member that maintains the filter element in position within the filter housing. The filter housing has a sidewall that comprises a transparent material, thereby allowing inspection of the oil within the filter without having to first remove the filter from an engine. Also provided is an oil condition indicator that allows a user to compare the color of the oil within the oil filter housing to one or more oil reference markers. The oil condition indicator is used to determine when the oil has reached its usable life and when the oil must be replaced.
