Abstract: A filter device is provided with a housing and an absorption material received in the housing. The absorption material absorbs and stores a water fraction of a liquid being passed through the absorption material. A bypass is arranged in the housing so that the absorption material can be bypassed. A throttling device correlated with the bypass controls flow through the bypass. The throttling device is a passive throttling element or an adjustable valve.

Abstract: A venting device for a housing, for example, a battery housing, has a gas-permeable and liquid-impermeable membrane attached to the housing so as to close off a venting opening of the housing. The membrane has a membrane section that overlaps and covers the venting opening. The membrane section has a predetermined bursting pressure. The membrane section deforms without being destroyed when pressure differences between the interior of the housing and the environment occur that are below the bursting pressure and when gas passes through the membrane section.

Abstract: The present invention relates to a decorative part, comprising an electroplated layer array applied to a plastic substrate. On the electroplated layer array, a PVD layer array having an adhesive layer, a mixed layer and a color-providing cover layer is provided, wherein the mixed layer provides for durability, in particular corrosion protection, and the necessary hardness of the surface.

Abstract: A filter pipeline for an air intake system of an internal combustion engine has a tubular body and a filter element arranged in the tubular body. The filter element is a filter bag of a flexible material that has an opening and is attachable in the area of the opening to the tubular body. The filter bag and an inner wall of the tubular body are provided with ribs projecting inwardly from the tubular body such that in a circumferential direction of the pipeline different spacings are provided between the filter bag and the inner wall of the tubular body.

Abstract: The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior.

Abstract: 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.

Abstract: A filter device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A liquid to be filtered is introduced into the filter housing and flows through the filter element. An overflow valve is arranged between an entry side and a clean side of the filter element and has a valve body. The overflow valve is in an open position when a pressure of the liquid at the entry side of the filter element exceeds a threshold value. The valve body of the overflow valve is a sealing hose placed between the entry side and the clean side onto a cylindrical supporting body arranged in the filter housing. Flow openings are provided in the cylindrical supporting body. The sealing hose is arranged at the clean side of the supporting body.

Abstract: A filter element comprising a filter medium which extends through an axial length between an end face at a clean air end and an end face at an unfiltered air end such that the filter medium separates an unfiltered air end of the filter element from a clean air end, in which the filter medium is circumferentially surrounded by a jacket and attached in a sealed manner to the jacket, and in which contours for securing the filter element in a filter housing are arranged on the jacket of the filter element.

Abstract: In an air connection unit (10) for an air filter housing (20, 21) having at least one fitting (11) into which is integrated at least one maintenance interval indicator or maintenance switch connection (12) and which is rotatably supportable in an opening in the air filter housing (20), an air guiding element adjacent the fitting (11) is formed as a corrugated tube (14) over at least a portion of its length. This enables a simple alignment, substantially without restoring forces, of the maintenance switch connection (12) relative to the air filter housing (20).
