In a method for producing two or more filter bellows, a bellows with a filter medium with fold edges is provided, wherein the filter medium is running in a running direction. A cutting path is carried out in the bellows with the filter medium in a direction that, at least in some regions, is transverse relative to the fold edges such that the filter bellows are produced in parallel and the cutting path creates end edge faces and/or side faces of the filter bellows and the filter bellows are embodied lying adjacent to each other and symmetrical or point-symmetrical relative to each other in the running direction and/or transverse to the running direction. A filter element with such a filter bellows and a filter system with such a filter element and filter bellows arranged in a filter housing are provided.

Method for producing filter bellows

A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is secured within the filter housing, wherein the non-return diaphragm is arranged on the functional carrier so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.

Liquid filtering device

An air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element with retaining geometry

A filter insert for a filter for filtering a fluid having] an inflow surface, and outflow surface, and a main throughflow direction. A filter body of the insert has a filter medium with pleats forming a pleated bellows, are arranged perpendicular to the main throughflow direction. A first number of the pleat edges form the outflow surface and a second number of the pleat edges on a pre-filtration side of the filtration body form the outflow surface. A first seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration on a surface formed by a first number of of end face of the pleats. A second seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration side on a surface formed by a second number of end faces of the pleats.

Filter insert for a fluid, in particular transmission oil

A filter element for fluids, including: a filter bellows made of a filter medium, the filter medium placed in the filter bellows along pleated edges in a zig-zag shape, in pleats that extend between opposite end edges of the filter bellows; wherein an end pleat having a pleated edge and an opposite free end margin is arranged on each opposite end face of the filter bellows, pleated edges that are consecutive along an end edge of a pleat end at opposite surfaces of the filter bellows; wherein a segment of one of the end edges extends obliquely to one of the pleated edges in such a manner that, in the one segment, the pleated edges on a first one of the opposite surfaces have a different length than the pleated edges of an opposite one of the opposite surfaces; and wherein the pleats are laterally sealed by the end edges.

Filter element having a filter bellows

A filtering system () includes a filter head () and a replaceable filter (). The filter head () has a feed line () and discharge line (). The replaceable filter () is removable and replaceably mounted onto the filter head () by a rotational and/or plug connection () and includes a housing () with at least one inlet () for oil to be filtered and at least one outlet (). The inlet () communicates with the feed line (). The outlet () communicates with the discharge line (). The housing () has a filtering element () that sealingly separates the inlet () from the outlet (). The filter head () includes an auxiliary oil line (). The replaceable filter () has a flow control element () that automatically closes or releases the auxiliary oil line () dependent on an operation and/or assembly condition.

Disclosed is an air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element having a specific retaining geometry

A filter device has, in a housing, a filter element and, downstream of the filter element, an outflow opening for discharging the cleaned medium. Between the filter element and the outflow opening there is arranged a diverting part, wherein on the diverting part there is formed an overflow region for the flow of the medium from the filter element to the outflow opening, and the outflow opening is situated at the same level as or below the overflow region.

Filter device, in particular liquid filter

A filter element of a filter system for filtering fluids has a filter medium with end faces. Terminal bodies, one each, are connected to one of the end faces of the filter medium, respectively. A support body extends between the terminal bodies. A first terminal body is connected by a toothed connection to the support body for transmitting a torque from the first terminal body onto the support body and from the support body onto the first terminal body.

Filter element and filter module

A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support.

Compact filter, method for producing a compact filter, and filter medium

A filtering device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A cover disk closes off the filter housing. The cover disk consists of two individual disks and a central flow connection connects the two individual disks. The two individual disks and the flow connection form a common plastic component.

Filtering system, in particular for filtering liquids in internal combustion engines

An oil filter unit for arrangement in the oil sump of an oil circuit, particularly in an automatic transmission. The oil filter unit has a multi-part filter housing with a filter chamber disposed therein such that an oil inlet and an oil outlet communicate with the filter chamber. A filter element is sealingly mounted in the housing between the oil inlet and the oil outlet. The filter element has a pleated filter medium, which is sealingly enclosed by a frame, and the frame has seal contours designed to cooperate with the contours of the filter housing.
