A smart multi-modal vehicular air filtration management system including a first filter element and a second filter element disposed in a fresh air housing, wherein the fresh air housing has an inlet and an outlet. Additionally, a third filter element is provided which is disposed in a cabin housing, the cabin housing having one or more inlet. A fluid channel arranged between the fresh air and cabin housing. Finally, a diverter is included which is disposed near an outlet of the fresh air housing, wherein the diverter is configured to cause air to flow through the fresh air housing selectively through one or both of the first filter element and the second filter element.

Smart multi-modal vehicular air filtering system and associated methods

The invention relates to a filter device () for filtering liquids, comprising: a filter element () having an interior () for accommodating a liquid, and a compensating element () made of elastically deformable material for accommodating a liquid volume that increases when the liquid freezes. The compensating element () is arranged in the interior (), and a gap (), in particular an annular gap, for accommodating the liquid is formed between the compensating element () and the filter element ().

Filter device for filtering liquids

A filter element () of a filter for fluid and a method for producing a filter element () are described. The filter element () has a filter medium () which is designed as a hollow body () and is closed at the periphery, at least with respect to an element axis (). The filter medium () is enclosed on at least part of its periphery and at least part of its axis by an electric heating jacket (). The heating jacket () is arranged in or on a fluid-permeable supporting hollow body (). The supporting hollow body () is open or can be opened, at least in an initial assembly of the filter element () on at least one peripheral side for arrangement on the filter medium hollow body ().

Filter element of a filter, heating cage for a filter element and a method for producing a filter element

A filter element for filtering liquids has a folded filter medium with outer fold edges and inner fold edges, wherein the inner and outer fold edges extend along a longitudinal axis of the filter element. A support body is provided with a first support body section and a second support body section, wherein the first support body section is facing the inner fold edges and hugs closely an envelope of the inner fold edges. An envelope of the outer fold edges and the second support body section hug closely at least sectionwise an outer circumferential surface of the filter element.

Filter element and filter arrangement

A filter element is provided with a folded bellows that has a first pleated section with parallel arranged first pleats and a second pleated section with parallel arranged second pleats. The first pleats of the first pleated section are positioned at an angle relative to the second pleats of the second pleated section. The end face edges of the first pleats of the first pleated section adjoin a first clean chamber. The end face edges of the second pleats of the second pleated section adjoin a second clean chamber. The second clean chamber is delimited by a longitudinal side of an edge-side pleat of the first pleated section. The first and second clean chambers are connected to each other. A filter insert with such a filter element is provided.

Pleated filter element

A filter () with a filter element () are described. A housing () includes at least one fuel inlet, fuel outlet () and a water outlet () for water separated from the fuel. The filter element () within the housing separates the fuel inlet () from the fuel outlet (). The filter element () includes a hollow body filter medium () flowed through radially. A water separation unit () with a hollow body hydrophobic fuel-permeable separating medium () separates water contained in the fuel and includes at least one support structure disposed in the flow path () in such a way that a precipitation gap () is realized between the filter medium () and the separating medium (). The precipitation gap () is connected with the water outlet ().

Fuel filter of an internal combustion engine and filter element of a fuel filter

A filter insert piece has a filter element with first and second pleated sections each having parallel pleats. The first and second pleated sections each have an inflow side. A first flat outflow side of the first pleated section and a second flat outflow side of the second pleated section adjoin a common clean chamber of the filter element. A length of the pleats of the first and second pleated sections is such that a spacing of an outwardly positioned pleat end face of the pleats at the first or second inflow side, respectively, relative to the center axis increases or decreases monotonic from pleat to pleat. The respective end pleats of the first and of the second pleated sections have a different length extension measured from the outwardly positioned pleat end face of the first end pleats or the second end pleats relative to the center axis.

Filter insert piece comprising a pleated filter element

A filter for fluid has a filter housing and a filter element disposed in the filter housing. An element-associated electrical connecting element associated with an electrical/electronic functional component is provided. A housing-associated electrical connecting element is provided. When the filter element is mounted in the filter housing, the element-associated electrical element and the housing-associated electrical connecting element are connected electrically with each other and form an electrical connection. A positioning assist device assists in positioning the element-associated electrical connecting element and the housing-associated electrical connecting element relative to each other.

Filter for fluid, filter element of a filter, and filter housing of a filter

A filter element () of a filter for fluid, particularly fuel, oil, water, urea solution or air, particularly of a combustion engine, particularly of an automobile, and a method for manufacturing same are described. The filter element () comprises a filter medium () structured as a filter medium hollow body () and closed circumferentially at least with respect to an element axis (). The filter medium () is enclosed at least partially circumferentially and at least partially axially by an electrical heating jacket (). The filter medium () has, on at least one front side, an end member () that is connected tightly at least to the filter medium (). After insertion of the filter medium hollow body () into the heating jacket (), the front side of the filter medium hollow body () is provided with an end member ().

Filter element of a filter and method for manufacturing filter element

Disclosed is a fuel filter () for fuel, in particular diesel fuel, of an internal combustion engine, in particular of a motor vehicle, and to a filter element of such a fuel filter. A housing () has at least one fuel inlet () for the fuel to be cleaned, at least one fuel outlet () for cleaned fuel, and at least one water outlet () for water which has been separated from the fuel. The filter element () is arranged in the housing (), said filter element sealingly separating the fuel inlet () from the fuel outlet (). The filter element () has a filter medium () which is designed as a hollow body and which can be permeated from the inside to the outside or from the outside to the inside in order to filter the fuel. The filter element () has a coalescing medium () designed as a hollow body for separating water contained in the fuel. The coalescing medium () is arranged downstream of the filter medium () in the flow path () of the fuel, around said filter medium, or in the interior () delimited by the filter medium. The coalescing medium () includes at least one regenerated-fiber coalescing system consisting of a coalescing material () which is suitable for coalescing water and which has at least 20 wt. % of regenerated fibers, preferably at least 50 wt. %.

Fuel filter of an internal combustion engine, and filter element of a fuel filter

A fuel supply device (), particularly for an internal combustion engine (), is equipped with a particulate filter and a water trap. In order to improve the separation effect, while simultaneously reducing the separation material that is required, it is proposed to configure the water trap () as a separate component connected downstream of the fuel filer () and to provide it with a first separation stage made of coalescent material and a second separation stage made of hydrophobic material, and to dispose the separation stages such that between them the fuel is diverted.

Fuel supply device, particularly for an internal combustion engine

The invention relates to a fuel filter () with a device for separating water from the fuel.
