Abstract: According to one representative embodiment, a fluid storage device for storing a first fluid in a second fluid storage container fillable with a second fluid includes a first fluid storage container, a first fluid inlet coupled to the first fluid storage container, and a first fluid outlet coupled to the first fluid storage container. The first fluid storage container is flexible. The first fluid inlet is communicable in fluid receiving communication with a first fluid source. The first fluid in the first fluid storage container is caused to drain from the first fluid outlet based on at least one of a first fluid level, a first fluid storage container pressure, a second fluid storage container pressure, the second fluid storage container filling with the second fluid, the first fluid outlet being opened for first fluid egress, and a first fluid outlet pressure.

Abstract: A filter cartridge that is designed to accommodate differences in lengths between an outer filter media and an inner filter media by providing a flexible connection between the inner filter media and the outer filter media. In addition, the endplates of the inner filter and the outer filter together define a gasket groove that receives a gasket. Using the endplates of the inner and outer filter media to define the gasket groove eliminates a mold parting line that can lead to fluid leakage.

Abstract: An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.

Abstract: A filtration assembly is provided for a fluid flowing in an engine or an apparatus that includes a tank on which a central tube is mounted for interaction with a filtration cartridge including an upper flange and a lower flange between which extends a filtration medium. The central tube is permanently mounted on a bearing member connected to the tank. The central tube bears a first seal and a second seal. The cartridge has a collar forming an extension of the lower flange, the collar being adapted for interaction with the first seal on the central tube in order to ensure tightness between the tube and the cartridge. The second seal is adapted for interaction with the bearing member and/or the collar in order to ensure tightness between the tank and the tube.

Abstract: A dual stage filter includes an outer filter with a first media and an inner filter with a second media. A barrier is between the first media and the second media. The barrier directs fluid flow between the first and second media. The barrier creates a flow path between the first and second media, such that a working fluid, which is desired to pass through the first and second media, is directed by the barrier and flows through the second media, and such that another fluid, which is not desired to pass through the second media, is directed by the barrier and separates from the working fluid. Using the barrier, the dual stage filter can employ either or both upward flow and downward flow to achieve efficient fluid separation, for example fuel water separation in an engine fuel filter.

Abstract: This invention relates to a hollow element designed to cooperate with a filter cartridge of a filter assembly for fluid circulating in an engine or a hydraulic equipment, of the type with support means for a filter medium included in the said cartridge, the said support means extending from connection means and designed with recesses between them through which the said fluid is free to flow, characterized in that the said support means extend from one of the said connection means to another following a path defining a spiral portion with a substantially constant slope.

Abstract: A filtering apparatus has a filter housing with a structure forming a recessed region on the filter housing configured to be directly engaged by a filter element in order to form an integral seal. The structure may include one or more protrusions that extend into the filter element itself, or into respective recess(es) of the filter element.

Abstract: A removable, spiral vane insert for receipt by a centrifuge rotor enclosure includes a unitary, molded plastic spiral vane portion including a spiral vane module and a baseplate that are all integrally joined together. The spiral vane portion further includes a tubular sleeve having a longitudinal axis corresponding to the axis of rotation for the rotor.

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.

Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.

Abstract: One embodiment is a replaceable filter element including a filter media having a first end, a second end and an interior cavity, and an endplate coupled to the first end of the filter media, the endplate including a projection extending from the endplate, the projection including a first portion, a flange and a second portion, the first portion extending from the endplate to the flange, the second portion extending from the flange. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.

Abstract: One embodiment is a replaceable filter cartridge including a plurality of stacked disks of filter media extending between a first endplate and a second endplate. A plurality of frame members extend axially between and connect the first endplate to the second endplate. The cartridge includes a compression assembly supported by the first endplate. The compression assembly includes at least one compression member operable to impart a compression force on said plurality of stacked disks of filter media thereby biasing said plurality of stacked disks of filter media in an axial direction toward the second endplate.
