摘要： A fluid filter is mountable on a connection flange having a central stand pipe and an exchangeable filter insert. The insert has a hollow cylindrical filter material body with two end plates on its end faces and is mountable on the stand pipe. A cup-shaped screw housing of the filter can be screwed to a free end of the stand pipe, and supports a seal on a free edge thereof, via which the screw housing is sealable against a connection flange sealing surface when mounted. The filter has a first arrangement on an end face area to center the end face area to the flange. The filter insert has a second arrangement on the end face area outer periphery for centering the screw housing free edge relative to the connection flange sealing surface. The second arrangement interacts in a centering manner with the screw housing free edge when installed.

摘要： The invention relates to a device for venting a crank casing of an internal combustion engine for a vehicle, having a plurality of venting ducts (13, 15, 53, 67, 84) by means of which gases flowing into a crank casing space (19) of the crank casing (7) can be conducted out of the crank casing space (19) again, wherein gas inlet openings (29, 55, 73), opening into the crank casing space (19), of the venting ducts are arranged in such a way that in a first defined inclination position of the internal combustion engine (3) a first venting duct does not dip with its gas inlet opening (29) into oil trough oil which is collected in an oil trough (5) of the internal combustion engine (3), and a second venting duct dips with its gas inlet opening (29, 55, 73) into the oil trough oil, wherein in a second defined inclination position of the internal combustion engine (3) which differs from the first inclination position the first venting duct (13, 67) dips with its gas inlet opening (29) into the oil trough oil and the second venting duct does not dip with its gas inlet opening (29, 55, 73) into the oil trough oil. According to the invention, a control device is provided by means of which a flow of fluid through the venting ducts can be shut off and released fluidically as a function of the inclination of the internal combustion engine (3), wherein in the first inclination position of the internal combustion engine (3) the control device releases the first venting duct and shuts off the second venting duct, and wherein in the second inclination position of the internal combustion engine (3) the control device releases the second venting duct and shuts off the first venting duct.

摘要： A filter material for a filter insert of a fuel filter for separating solid particles and water droplets from fuel. The filter material comprises a particle filter medium layer through which the fuel flows first during use and at least one coalescer medium layer which lies on the particle filter medium layer on the outflow side. At least one coalescer medium layer is gradient-free in the flow direction with respect to the geometrical structure and/or physical properties and/or chemical properties of the layers. The at least one coalescer medium layer has a thickness measured in the flow direction which is maximally as large as the thickness of the particle filter medium layer measured in the flow direction.

摘要： A fluid filter comprising a housing with a fluid inlet and a fluid outlet, a central vertical pipe that forms the fluid outlet, a filter cartridge pushed onto the vertical pipe, and a valve unit. The vertical pipe has a screw thread on each axial end region for connection into the housing on one side and to a filter connection flange on the other side, and at least one passage in the region lying between the end regions. In one aspect, the vertical pipe has, on the outer periphery of the region lying between the axial end regions, guide elements for at least one valve body of the valve unit and/or guide elements and retaining elements for a valve spring support of the valve unit.

摘要： A fluid filter comprising a housing, a fluid inlet and a fluid outlet, a filter element separating a raw side and a clean side from one another, and a valve unit. The valve unit comprises a valve plate arranged concentrically in the housing and having the shape of a circular ring disc, having valve openings and a flexible circular-ring-disc-shaped valve membrane arranged on the valve plate. The filter element comprises an axially protruding pressure-exerting ring shaped as a circumferential annular collar on the end face thereof facing the valve unit when installed. When installed in the housing, the filter element, with an end face of the pressure-exerting ring, presses the valve membrane axially onto the valve plate. The valve membrane, with the membrane region thereof pressed by the pressure-exerting ring onto the valve plate, forms a seal separating the raw side from the clean side of the fluid filter.

摘要： A filter having a filter housing, an inlet for liquid to be filtered and an outlet for filtered liquid. An exchangeable filter insert separates an unfiltered side and a filtered side of the filter. A filter bypass valve has a valve seat and a valve body guided so as to be movable relative to the valve seat and preloaded in the closing direction. The valve seat is fixed to the filter. The valve body is guided in the filter so as to be fixed to the filter. A spring that preloads the valve body in the closing direction is guided in the filter so as to be fixed to the filter. The filter insert has a spring support that, in the state in which the insert is placed into the filter housing, supports and pre-stresses the spring at its end facing away from the valve body.

摘要： A liquid filter having a housing with a removable cover and an exchangeable cylindrical insert enclosed by two end disks. The filter has a bypass valve and the upper end disk has a central valve seat interacting with a valve body. The housing has a central discharge duct, with a closure pin fixed in the duct which is axially adjustable between closed and open positions. The filter has a valve body carrier connected, with limited axial displaceability, to the pin. The carrier, on its free end, has the bypass valve body, and onto which the insert end disk is mountable. The carrier is preloaded with a force, acting in the closing direction of the valve via a housing spring. During mounting of the insert onto the carrier, a force acting in the closing direction of the closure pin can be exerted directly on the pin by the insert.
