Disclosed is a filtration device for a liquid, including: at least two superimposed layers of filter media having weld lines creating strips between them, the layers of filter media having weld lines being superimposed such that the weld lines of one layer form, with the weld lines of the other layer, a mesh structure when viewed at an angle normal to the layers of filter media; a first external face and a second external face each being produced at least locally from a water-permeable material, the layers of filter media being positioned between the external faces; and an intake connector used for drawing liquid in through the filtration device.

A particle separation system may comprise a vessel having at least one side wall and a bottom wall forming an internal chamber within the vessel, a filtration unit positioned within the vessel and including a first filtration pack including a first plurality of filter elements, an inlet for moving pre-separated fluid into the vessel, and an outlet in fluid communication with the filtration pack for moving processed fluid out of the vessel, a rate of pre-separated fluid flow into the vessel and a rate of processed fluid flow out of the vessel each being between about 10 and about 1000 gallons per minute (GPM) and a flux within the filtration unit is less than or equal to about 0.05 gallons per minute per square foot (GPM/ft.sup.2).

A strainer for a fuel pump according to the present invention includes: a communicating pipe including a flow path formed to communicate with a fuel inlet of the fuel pump; a filter including an internal space in which a fuel flows and coupled to the communicating pipe so that the internal space communicates with the communicating pipe; and a rib disposed in the filter and coupled to the communicating pipe, in which the filter includes a first filtering portion extending in a length direction with respect to the communicating pipe, a connecting portion extending in a width direction at an edge of the first filtering portion, and a second filtering portion extending in the length direction at the connecting portion and spaced apart from the first filtering portion in the width direction. Therefore, the strainer may have a relatively large filtering area and a small size.

A method including the steps of moving fluid through an inlet into a vessel, the vessel being at atmospheric pressure and having at least one side wall and a bottom wall forming an internal chamber within the vessel. The method further includes moving the fluid into and through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft.sup.2), and moving the fluid processed by the filtration unit to an outlet and out of the vessel.

There is provided a filter for filtering particles in a container of fluid. The filter comprises a flow director comprising a hub, a plurality of radial blades extending from the hub and a plurality of vanes concentric about the hub. The blades and the vanes intersect to form a grid which collectively define a plurality of openings, each opening extending between a first face and a second face, where a cross-sectional area of each opening decreases from the first face to the second face. The filter further includes a skirt coupled to the perimeter of the flow director for maintaining the flow director in spaced relation from a bottom of the container. The decrease in cross-sectional area of the openings in the grid helps to prevent particles from travelling from a position below the flow director to a position above the flow director.

The present disclosure provides a method of manufacturing a filter, wherein the filter comprises a filter body formed of a porous filtration material and a plastic support structure, the method including performing a first additive manufacturing step to form an initial portion of the support structure; positioning filtration material above or on the initial portion; performing a second additive manufacturing step to form a secondary portion of the support structure such that the filtration material is between the initial and secondary portions. Additionally, the filter body can be enclosed by positioning a first portion of the filtration material to overlay a second portion of the filtration material; and connecting the first portion of the filtration material to the second portion of the filtration material to define a pocket within the filter body, the support structure configured to maintain spacing between the first and second portions of the filtration material.

A drive power transmission apparatus for a vehicle, includes an oil pump, an oil strainer connected to the oil pump, a differential gear mechanism, and a housing case including a first chamber in which the oil strainer is disposed and a second chamber in which the differential gear mechanism is disposed, the second chamber communicating with the first chamber via a communication port, and the oil strainer has a suction port that is not surrounded by a rib, and has a first rib disposed between the suction port and the communication port.

A suction filter device for filtering oil includes a filter housing having an oil inlet opening and an oil outlet opening, via which a filter housing interior can be fluidically connected to a suction line. An oil filter medium is arranged in the filter housing interior between the oil inlet opening and the oil outlet opening, so that, by means of negative pressure generated via the suction line within the filter housing interior in relation to an environment of the filter housing, an oil flow can be generated from the oil inlet opening through the oil filter medium and through the oil outlet opening. Further, an oil-permeable and air-impermeable air separation medium is included. The air separation medium is arranged upstream of the oil outlet opening when a vacuum is generated via the suction line within the filter housing interior in relation to an environment of the filter housing.

A sender assembly that has a compact state, which may allow a pump assembly including the sender assembly to be easily inserted into an opening of a fluid tank. For example, the pump assembly may be insertable into the opening of the fluid tank while a longitudinal axis of the pump assembly remains coaxial with the opening. When in the compact state a rotatable arm and a float of the sender assembly may be entirely within or deformable to be within a predetermined envelope that has a radial extent less than the opening of the fluid tank to allow the sender assembly to be inserted straight into the opening. The predetermined envelope may be coaxial with the longitudinal axis and have a cross-section transverse to the longitudinal axis that matches the opening of the tank.

A fuel strainer includes a first panel of filtration media having a filtration media first layer and a filtration media second layer and a second panel of filtration media having a filtration media first layer and a filtration media second layer such that the filtration media second layer is between the filtration media first layer of the second panel of filtration media and the filtration media second layer of the first panel of filtration media such that an interior space is formed between the first panel of filtration media and the second panel of filtration media which receives fuel that passes through the first panel of filtration media and the second panel of filtration media. A magnet is captured between the filtration media first layer and the filtration media second layer of either the first panel of filtration media or the second panel of filtration media.
