Abstract:
One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.
Abstract:
A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.
Abstract:
An automatic draining system is provided. The system includes a floating valve having a density less than a first fluid and greater than a second fluid. The floating valve has a floating position that allows the first fluid to pass through a floating valve opening when the floating valve compartment is filed with the first fluid, and a sealing position that prevents the first and second fluids from passing through the floating valve opening when the floating valve compartment is not filled with the first fluid. Also included is a solenoid valve in fluid communication with the floating valve compartment. The solenoid valve has a solenoid opening that is open when the solenoid valve is energized and is closed when the solenoid valve is de-energized. Further included is a filter media downstream of the solenoid valve that filters the first liquid prior to the first fluid exiting the system.
Abstract:
A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control valve is provided on a standpipe to control the flow of fuel into the standpipe. The valve has a component that has a first position at which any flow through the flow passage past the valve is insufficient to permit engine operation, and a second position at which a greater amount of flow through the flow passage is permitted by the valve in an amount sufficient to permit engine operation, and the component rotates about the longitudinal axis when it moves from the first position to the second position and from the second position to the first position.

Abstract:
A valve assembly that is useable with a fuel filter housing to control the flow of fuel through the fuel filter housing. The valve assembly comprises two primary parts that are connected together via a snap connection, and when the valve assembly is installed on the fuel filter housing, means on the fuel filter housing prevent disconnection of the snap connection. One or both of the primary parts of the valve assembly can be provided with a tamper evident feature that will indicate whether someone has tried to remove or disassemble the valve assembly.
Abstract:
A “no filter, no run” filtration system that is designed to verify that an appropriate filter cartridge is installed. A flow control sleeve is provided on a standpipe to control the flow of fluid, for example fuel, into the standpipe. The sleeve can be axially moveable between closed and open positions, with one or more members on an installed filter cartridge designed to release the sleeve to permit the movement from the closed position to the open position to allow fluid flow. A spring acts on the sleeve to bias the sleeve back to the closed position upon removal of the filter cartridge. The sleeve can also be designed without axial movement, but nonetheless is configured to be opened and closed to control fluid flow into the standpipe.
Abstract:
A filter cartridge with a valve actuating protrusion having a sliding surface that is configured to engage with a valve, with the sliding surface being tapered so that a first portion of the sliding surface that engages the valve is wider than a second portion of the sliding surface that engages the valve, and the sliding surface is configured so that the first portion engages the valve before the second portion. The valve, which can be in any fluid passage of a filter housing, includes a plurality of spring arms. Engagement between the spring arms and the sliding surface creates a lifting force which opens the valve.
Abstract:
A fluid filter is described, where a drain valve is configured to move back and forth into open and closed positions. The drain valve and a filter cartridge are in a structural arrangement such that the drain valve is put in an open position before the filter and/or a filter element therein can be serviced or replaced.
