A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. One functional element has an assembly ramp passing into a first support region perpendicular to the connection axis. The other functional element has a slide region adjoined by a second support region perpendicular to the connection axis. In connection end position, first and second support regions are positioned on top of each other relative to the connection axis.

Treatment device for treating in particular liquid fluids, and treatment unit and connection head of a treatment device

A filter holder for a filter element that has an oval-shaped cross section, with a receiving section receiving the filter element, a fluid inlet and a fluid outlet. The fluid inlet is arranged such that an inflow direction of the fluid to be filtered is oriented in the direction of a lateral surface of the filter element in order to separate particles contained in the fluid onto a wall of the receiving section with the aid of centrifugal force.

Filter holder, filter element and filter arrangement

A filter element has a filter body which is closed on at least one end face by an end disc, wherein the end disc is formed from a potting compound, and has a stabilization device which is surrounded at least in some areas by the potting compound. At least one data storage unit is arranged on or in the stabilization device.

Filter element, filter system comprising a filter element, and method for producing a filter element

A filter element for a filter for filtration of a fluid is insertable along an insertion direction into the filter. The filter element is provided with a filter medium to be flowed through along a main flow direction. The filter element has a clean side and a raw side. A sealing surface surrounds the filter medium, wherein the sealing surface, interacting with a filter housing of the filter when the filter element is in an installed state in the filter housing, separates the clean side from the raw side. A support edge exerts a force on the sealing surface by interacting with the filter housing of the filter when the filter element is in the installed state in the filter housing. The sealing surface and the support edge are positioned at an acute angle relative to each other.

Filter element with an oblique sealing plane

A filter holder () for a filter element () has an oval-shaped cross section, a receiving section () for a filter element (), a fluid inlet (), and a fluid outlet (). The fluid inlet () is arranged such that an inflow direction (E) of the fluid (L) to be filtered is oriented in the direction of a lateral surface () of the filter element () such that the fluid (L) to be filtered flows tangentially around the filter element () in order to separate particles () contained in the fluid (L) onto a wall () of the receiving section () with the aid of centrifugal force.

Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.

Air filter element and air filter

A filter device () for an internal combustion engine includes a separator that is embodied as a cyclone preseparator (), a main filter element () exchangeably arranged in a housing compartment () of the filter housing (), and a secondary filter element (. The housing compartment () includes insertion stays (). The main filter element () is embodied in as a double bellows filter including a first radially inwardly positioned filter bellows () and a second radially outwardly positioned filter bellows () surrounding it. Upon closing of a servicing housing cover () a sealing force is generated that acts onto the main filter element () and is maintained in the closed state of the servicing cover ().

Filter mechanism for internal combustion engines

The invention relates to a filter () having a drainage outlet (), which can be tightly connected to a connecting head (). It is proposed to use an insertion seal having radially opposite sealing surfaces of an outer seal () and an inner seal ().

Filter having a drainage connection

The invention relates to a filter device (), in particular for filtering intake air of an internal combustion engine. The filter device () comprises a separator that is embodied in particular as a cyclone preseparator (), moreover a main filter element () exchangeably arranged in a housing compartment () of the filter housing (), as well as a secondary filter element () that in the flow direction of the fluid to be cleaned is arranged downstream. The housing compartment (), for facilitating premounting of the main filter element () therein, comprises insertion stays (). The main filter element () is embodied in particular as a double bellows filter, comprising a first radially inwardly positioned filter bellows () and a second radially outwardly positioned filter bellows () surrounding it. Upon closing of a servicing cover () that closes the housing compartment () a sealing force is generated that acts onto the main filter element () and is maintained in the closed state of the servicing cover ().

A filter is disclosed that includes a filter cup, a filter insert inserted into the filter cup and having a substantially cylindrical shape and a terminal disk arranged at an end face of the filter insert and connected to an end of the filter cup. The terminal disk includes a circumferential rim configured to engage the end of the filter cup and is provided with locking means that positive-lockingly connects the terminal disk and the filter cup.

Filter

A filter system for a fluid having a cup-shaped housing releasably connected to a connecting head and a filter element arranged in the housing, in which the releasable connection is formed by at least one connecting element formed on the connecting head which engages a connecting element formed by a part of the filter element in combination with a part of the cup-shaped housing such that the connection between the housing and the receiving head can only be produced if a proper filter element is installed in the housing.

Filter system

A liquid filter, especially oil filter for an internal combustion engine, having a cup-shaped housing with a liquid inlet and a liquid outlet, a filter element arranged with a seal between the inlet and outlet, and a one-piece barrier membrane arranged in the area of the opening of the cup-shaped housing such that the liquid inlet and/or the liquid outlet can be closed by the barrier membrane.

Liquid filter

A compact filter element with a large filter surface area having inner and outer rings of filter material with an annular space between them, such that fluid to be filtered can be introduced into the annular space between the rings of filter material and a portion thereof can flow through the outer ring of filter material to the periphery of the filter element and another portion thereof can flow through the inner ring of filter material to the center of the filter element; at least one fluid-permeable support member for the filter material, and at least one end disk on an axial end face of the filter element affixed to the rings of filter material in a sealed manner, in which the end disk has a centrally arranged inlet opening for the fluid to be filtered and one or more radially extending distributor channels leading from the central inlet opening to at least one eccentrically arranged outlet opening which opens into the annular space between the rings of filter material to admit fluid to be filtered to the annular space.
