A filter device for treating fluids, in particular for filtering fluids such as fuel, oil, or water, has a housing () with a housing pot (), a housing cover (), at least one inlet () for the fluid to be treated, and at least one outlet () for the treated fluid. A connecting head () has at least one feed () for the fluid to be treated and connectable to the at least one inlet (), and/or at least one discharge (). The connecting head () and the treatment element () can be connected to each other by means of a releasable bayonet-type connecting device () through the execution of a rotational/plug-in movement about a connecting axis () of the treatment device ().

Treatment device for treating fluids, in particular liquid fluids, and treatment element of treatment device

A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

Method for producing a filter element provided with a sealing part

A filter device has a filter housing and a round filter element received in the interior of the filter housing. The round filter element has a filter medium body with a wall flowed through radially relative to a longitudinal axis of the filter medium body by a fluid to be purified. The round filter element has a first end disk and a second end disk arranged at opposed end faces of the filter medium body. The filter medium body has an inwardly positioned flow space inside the filter medium body that is the raw side of the round filter element. A support grid is arranged externally at the wall of the filter medium body. The filter housing has a housing cover with a flow guiding rib arranged at an inner side of the housing cover facing the interior. The flow guiding rib projects into the inwardly positioned flow space.

Filter device and round filter element, in particular for gas filtration

A filter device includes in a filter housing a hollow cylindrical filter element having frontal end plates, a flow opening being made in one of the end plates. In order to interlockingly secure a pipe connection piece that communicates with the flow opening, a cover has a radial collar which forms an axial stop for the pipe connection piece.

Filter device, in particular liquid filter

A filter system () has at least one filter element (), a filter housing () having at least one first housing part and one second housing part, in particular a lid (), as well as a coupling device (). The coupling device () thereby has at least one first coupling part () and at least one second coupling part () that corresponds to it for removable coupling of the at least one filter element () to the second housing part (). The first coupling part () has one or a plurality of first latching means () and control surfaces (). The second coupling part () has one or a plurality of second latching means () that can be brought into operative connection with the one or a plurality of first latching means () and control surfaces (). At least the first and the second latching means () can be brought into functional connection when joined, and the control surfaces () and the second latching means () can be brought into operative connection when first and second housing parts () are released. The second latching means () each have three bevels (), at least two of which work together with the control surfaces () to release the second housing part () from the filter element () upon a relative rotation of the filter element () around the longitudinal axis (L) counter to the second housing part ().

Filter system and filter element

A filter device has a cup-shaped filter housing and a filter element disposed in the filter housing. A filter head is connectable to the filter housing and forms a cover for the filter housing. A spring element is provided that is acting on the filter element. The filter head has at least one first form-fit element. The filter housing has at least one second form-fit element for interacting with the at least one first form-fit element. The spring element is arranged such that the filter head and the filter housing for reaching a closed position, in which the at least one first form-fit element and the at least one second form-fit element engage each other, are movable relative to each other axially against the force of the spring element. The spring element clamps the filter element axially between filter head and filter housing in the closed position.

Filter housing with locking form-fit elements and spring loading a filter element in the housing

A filter device includes in a filter housing a hollow cylindrical filter element having frontal end plates. A port having a first sealing element is incorporated into a cover the filter housing, said sealing element being arranged coaxially relative to a second sealing element in a flow opening in the end plate.

A filter cartridge for a filter apparatus, including: a filter element that encloses an clean space within the filter element, at least partially; wherein the filter element has an outflow opening in flow communication with the clean space in the filter element; wherein the filter element has a longitudinal axis extending through the filter element and through the outflow opening; wherein a hollow base for connecting to a housing-side fastening element is arranged on or in the clean space; wherein an interior of the hollow base is sealed off from the clean space in a flow-tight manner.

Filter cartridge for a filter apparatus

A filter element, in particular for filtering the intake air of an internal combustion engine, is provided with a filter medium and a sealing device extending at least partially circumferentially around the filter medium, wherein the sealing device is made from a foamed thermoplastic elastomer, and wherein the sealing device is injection molded using a plastics injection molding method.

Filter element and method for producing same

A filter element for filtering a fluid, including: a filter bellows made of a filter medium folded into zig-zag-shaped pleats along fold edges, each pleat extending between opposing end edges of the filter bel-lows, and being laterally sealed at the end edges by means of at least one sealant track or a sideband; wherein the filter bellows includes a first element section; and a second element section, which include each on opposing end faces end edge surfaces and that substantially run parallel to one another, wherein, from one element section to another element section, at least one of the end edge surfaces changes direction.
