A sock style filter is disclosed that incorporates the embossing of filtration media to create rigid raised geometry embodiments that prevent collapse between the upper and lower filtration media sides of the filter to maintain and ensure a flow passage of fluid inside the filter for flow to the pump or downstream system. The embossed rigid embodiments keep the filtration media from collapsing under suction and eliminates the use of secondary inserted structures; such as a plastic comb or folded net, or injection mold plastic ribs or bones onto or around the filtration media.

Forming filtration media for maintaining flow passage through a sock style filter

An in-tank fluid filter has a filter body made of porous material and a plastic outlet port attached to the filter body for connecting the filter to a pump. A plastic retainer is integrally formed on the outlet port, the retainer comprising a tab extending in a plane perpendicular to the flow axis, the tab having a first surface proximate the pump and a second surface remote from the pump, the tab having an aperture extending from the first surface to the second surface with an effective cross-section at the first surface that is larger than the post cross-section and that is reduced toward the second surface to an effective cross-section that is smaller than the post cross-section.

In-tank fluid filter with plastic retainer

A filter includes first and second axially spaced end caps having filter media extending axially between the end caps and extending in a closed-loop around a perimeter defining a hollow interior communicating with an axial flow opening through one of the end caps. One or more columns extend axially in the hollow interior between the end caps and are laterally spaced from the axial flow opening and have hollow sub-interiors for receiving one or more posts extending axially thereinto from a base for mounting the filter to the base in axial compression and with a wiper seal.

Filter with support columns

A fuel filter includes features adapted to collect and drain static electrical charges occasioned by the passage of fuel therethrough. The filter includes a two-piece plastic housing having an end cap and a cylindrical portion with an end defining inlet and outlet fittings. The filter element is cylindrical and includes an outer perforated metal shell, an intermediate pleated paper filter and an inner perforated metal shell. Both metal shells are secured and electrically coupled to an electrically conductive end cap. The electrically conductive end cap is electrically and mechanically connected to a conductive, circular spring. The spring engages a ground pin which extends through the cylindrical portion of the housing and may be connected to a suitable ground to drain off static electrical charges generated by fuel flowing through the filter. The other end of the filter element is either embedded in the housing end cap or, in an alternate embodiment, a smaller end cap which is received in the housing end cap.

Fuel filter assembly having a conductive spring

A filter ring for use around the circumferential fuel and timing fluid inlets of a diesel engine fuel injector or similar fluid conducting body. In a first preferred embodiment, the filter ring includes first and second semi-annular, band-shaped filter portions, an integrally formed hinge for pivotally interconnecting the filter portions, and a snap latch mechanism for releasably connecting the opposite ends of the filter portions. In a second preferred embodiment, the filter ring includes a pair of substantially identical snap latch mechanisms for detachably interconnecting the filter portions. The snap latch mechanism is formed from a bead or projection that extends substantially along the entire height of the end of one of the filter portions, and a complimentarily shaped groove on the end of the other filter portion. The thickness of the bead and groove is less than the thickness of the opposite ends of the band-shaped filter portions so that the inner diameter of the resulting filter ring seats securely around a complimentarily shaped annular recess in the fuel injector. The hinge and snap latch mechanisms allow the filter ring to be removed without damage, whereupon it may be cleaned and reused many times before requiring replacement.

Snap latch filter ring for a fuel injector

A filter ring is provided that is particularly adapted for use around the circumferential fuel and timing fluid inlets of a diesel engine fuel injector. The filter ring includes first and second semi-annular, band-shaped filter portions, an integrally formed hinge means for pivotally interconnecting the filter portions, and a snap latch mechanism for detachably connecting the opposite ends of the filter portions. The snap latch mechanism is formed from a bead that extends substantially along the entire length of one of the filter portion ends, and a complementarily-shaped groove on the end of the other filter portion. The thickness of the bead and groove is less than the thickness of the opposite ends of the band-shaped filter portions so that the inner diameter of the resulting filter ring seats securely around a complementarily-shaped annular recess in the fuel injector. The snap latch mechanism allows the filter ring to be removed without damage, whereupon it may be cleaned and reused many times before requiring replacement.
