  • Patent number: 11198077
    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.

  • Patent number: 8845897
    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.

  • Patent number: 8496816
    Abstract: A fuel heater module and a water-in-fuel sensor module are disclosed that are configured to be connected to an outside surface of a filter assembly. The fuel heater module includes an inlet port and an outlet port with a heating element positioned in the fluid path between the inlet and outlet. A thermostat is included for controlling operation of the heating element. The water-in-fuel sensor module is configured to detect water in the filter housing that it may be drained from the filter housing. Both modules are configured to be attached to an outside surface of the filter housing thereby being readily replaceable.

  • Patent number: 8425772
    Abstract: A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear.

  • Patent number: 8002981
    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.

  • Patent number: 7854839
    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.

  • Publication number: 20100006483
    Abstract: According to one embodiment a replaceable filter element includes a substantially annular filter media extending from a first end to a second end and has an exterior, a substantially hollow interior, and a first permeability. A first end plate is coupled to the first end of the substantially annular filter media. The first end plate includes an aperture leading to the substantially hollow interior of the substantially annular filter media. The replaceable filter element includes a filter media piece positioned adjacent the second end of the substantially annular filter media and has a second permeability less than the first permeability. The replaceable filter element includes an outer wrap extending from the second end of the substantially annular filter media along a portion of the exterior of the substantially annular filter media. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.
