摘要： A combined full flow and bypass oil filter for internal combustion engines includes a generally cylindrical filter body and a generally cylindrical filter head which is threadedly attached to the filter body. The filter head includes an inlet and an outlet and the flow path between the inlet and outlet extends through the filter body. Disposed within the filter body is a generally cylindrical and hollow full flow filtering element and a generally cylindrical and hollow bypass filtering element. The incoming flow of lubricating oil passes through the outer diameter surfaces of the full flow and bypass filtering elements and exits from these filtering elements through their hollow interiors. Concentrically positioned in the exiting flow path of the full flow filter is a Venturi nozzle which creates a low pressure zone. An outlet flow conduit is disposed in flow cooperation with the exiting oil flow through the bypass filtering element and the exit opening of this flow conduit extending from the bypass filtering element is positioned within the low pressure zone of the Venturi nozzle. The pressure differential across the two filtering elements creates a forced flow through the bypass filtering element and the filtered oil through both elements combines as part of a single flow loop.

摘要： A fuel filter constructed and arranged for fuel-water separation which is designed with an integral fuel pump includes a unitary housing designed with a fuel filter cavity for receipt of a fuel filter cartridge, and a pump receptacle cavity for receipt of a fuel pump. A separating wall is disposed between the fuel filter cavity and the fuel pump cavity and this wall defines a flow passageway for fuel flow communication between the fuel pump and the fuel filter. Included as part of the fuel filter assembly is a lid designed to attach over the fuel filter cavity of the unitary housing and a lid designed to attach over the pump receptacle cavity of the unitary housing. The combining of the fuel filter cartridge and the cooperating fuel pump within the same unitary casting provides design efficiencies and economies.

摘要： An apparatus, system, and method are disclosed for multistage water separation. A first separation layer separates water droplets from a fuel flow by repelling the first water droplets. A coalescing layer may coalesce fine water droplets in the fuel flow. In one embodiment, a centrifugal separator directs the fuel flow tangentially to a filter wall and the centrifugal force of the fuel flow directed tangentially along the filter wall biases water droplets from the fuel flow. A second separation layer separates second water droplets from the fuel flow.

摘要： A filter cartridge for use in filtering fluids, for example fuel, lubrication, hydraulic and other liquids, as well as air. The filter cartridge is a filter-in-filter design with an inner filter and an outer filter. The inner filter and the outer filter, for example the bottom end plates thereof, are connected to each other via a snap fit connection mechanism. During manufacture, the inner filter can be inserted into the outer filter, with the snap fit connection mechanism retaining the inner filter in the outer filter.

摘要： The present invention provides a filter assembly containing a filter element and a container as a depot for a liquid additive. The container can include an inlet and an outlet, which are configured to allow a liquid to flow into the container mix with the contained additive and then flow out into the system. It has been observed that a liquid flowing through a filter assembly exhibits a pressure gradient within the filter. Consequently, the inlets and outlets to the container can be positioned to take advantage of the pressure gradient to enhance the addition of the additive to the liquid in the filter assembly.

摘要： A filter assembly includes a housing and an inner post with a fluid inlet passage extending in the housing. An outer post surrounds the inner post to define a fluid outlet passage. A filter cartridge is received around the inner post and the outer post. The filter cartridge includes a filter element. A first endplate, which defines a first opening, is attached to a first end of the filter element. A first seal is received in the first opening to seal between the inner post and the first endplate. A second endplate, which defines a second opening, is attached to a second end of the filter element. A seal is received in the second opening to seal the outer post with the second endplate. The housing and the filter cartridge define an outer cavity. The fluid inlet passage opens into the outer cavity to minimize back flushing of contaminants.

摘要： A liquid filter (10) housing an annular filter element (16) has an annular space or inlet chamber (24) between the filter element and the housing and viewable through the housing such that an operator can see the level of liquid in the inlet chamber as an indication of when to replace the filter element, the higher the level of liquid in the inlet chamber the greater the pressure drop across the filter element. A change interval plugging indicator (102), preferably part of the filter element, is provided by a gas trap and pressure responsive release mechanism (104) trapping gas in the upper section (23) of the inlet chamber until a designated release pressure is reached, corresponding to a desired terminal pressure, to prevent premature plugging indication otherwise indicated by rising liquid level in the inlet chamber. Accurate and reliable calibration is enabled by separating the filtration function and the plugging indication function.

摘要： A liquid filter (10) housing an annular filter element (16) has an annular space (24) between the filter element and the housing and viewable through the housing such that an operator can see the level of liquid in the annular space as an indication of when to replace the filter element, the higher the level of liquid in the annular space the greater the pressure drop across the filter element. The rise in liquid level in the annular space is delayed for applications where the filter element is otherwise changed prematurely and has a longer life than otherwise indicated by the rising liquid level in the annular space. The delay is provided by a liquid and vapor impermeable sleeve (50) trapping vapor. In a further aspect, the sleeve is provided with apertures (70, 72, 74, 90, 92) filled by liquid-soluble buttons (76, 78, 80, 94, 96) providing filter element change interval indication, including advance sequential indication.
