Abstract:
At least one embodiment of the invention pertains to a fluid filter having a fine media element and a coarse media element inside a housing. The fine media element has a plurality of apertures through a flange around the periphery of the fine media element.
Abstract:
A filter device having a vent device for inhibiting formation of a vacuum in the filter device. The filter device includes a drum for receiving the liquid wherein the drum includes a drum headspace. The filter device also includes filter sets for filtering the liquid. The drum is rotated to enable cleaning of filter media. The filter device also includes a frame having spaced apart supports for supporting each of the filter sets. A fluid passageway extends between the supports, wherein the fluid passageway provides fluid communication between the tank headspace and a filter set to vent a filter set.
Abstract:
A pump unit having a fuel pump and a suction filter is provided in a sub tank of a fuel tank. A filter element sheet for the suction filter is formed in a cup shape, a bottom wall portion of which faces to an inner bottom surface of the sub tank. A suction port of the fuel pump is opened to a fuel passage formed in the inside of the suction filter, so that filtered fuel is sucked into the fuel pump. Multiple mountain fold portions and multiple valley fold portions are formed on a side wall of the cup-shaped filter element sheet, to thereby increase surface area for filtering the fuel.
Abstract:
A filter includes a filter element (1) having a filter medium (106) pleated in a zigzag manner, with a raw side (105) and a clean side (104). Filter medium sections (120), which extend on either side of the raw-side pleat tips (102a) to adjoining raw-side pleat bases (103a), include a first bend (552) toward the raw side (105), and behind that a second bend (554) toward the clean side (104), in each case viewed from the raw-side pleat tips (102a).
Abstract:
The instant disclosure relates to a double-layer filter structure disposed in an oil filter. The double-layer filter structure includes two individual filter media for removing impurities of different sizes in the engine oil. The double-layer filter structure includes a first filter medium and a second filter medium. The first filter medium has a plurality of wave-shaped and annularly arranged first folding portions. Similarly, the second filter medium has a plurality of wave-shaped and annularly arranged second folding portions. Each of the first folding portions has a mating portion retained by the second folding portions correspondingly.
Abstract:
The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).
Abstract:
A hydraulic filter element may include cylindrical filter body having a filter material folded in a star-shaped manner. A cylindrical inner frame may be radially supported on an inside of the filter body. A cylindrical sleeve may be permeable to a respective hydraulic medium and arranged radially against the outside of the filter body under prestress, wherein the sleeve may include a knitted textile material.
Abstract:
A filter includes a filter element (1) having a filter medium (106) pleated in a zigzag manner, with a raw side (105) and a clean side (104). Filter medium sections (120) extend on either side of the raw-side pleat tips (102a) to adjoining raw-side pleat bases (103a) include a first bend (552) toward the raw side (105), and behind that a second bend (554) toward the clean side (104). A plurality of elongated depressions (656) are formed on the raw side (105), which extend between pleat tips (102a) and pleat bases (103a) approximately perpendicular to pleat edges (F) and implement corresponding elevations (658) on the clean side (104) such that, in a raw-side pleat intermediate space (148a), in each case, two depressions (656) on the two medium sections (120) delimiting the pleat intermediate space (148a) are located directly opposite of each other and each form a flow channel (660).
Abstract:
A filter includes a filter element (1) having a filter medium (106) pleated in a zigzag manner, with a raw side (105) and a clean side. On the raw side (105) and/or on the clean side of the filter medium (14; 106), a plurality of oblong adhesive sections (122) are disposed along at least two adhesive tracks (101) on the filter medium (106), which run obliquely or perpendicularly to the pleat edges (F) at least in some sections. Each adhesive track (101) having at least one adhesive section (122) and at least one adhesive interruption (107). The adhesive interruptions (107) are offset from each other such that in a medium section (120) the adhesive interruptions (107) do not form a passage (126) that runs continuously parallel to the pleat edges (F).
Abstract:
Methods and apparatus for increasing the duration of uninterrupted filtering flow by using crossflow filtration and ultrasonic energy in difficult to filter process liquids (e.g. of the kind having (1) a carrier liquid, (2) coalescing solids particles which tend to adhere and bridge filter element gaps sized substantially larger than such particles, and (3) larger impurity elements to be filtered out of such process liquid and sized larger than such filter element gaps).
