摘要： A separator plate having a receptacle for a drive shaft that defines an axis of rotation. Such plate, which includes a first annular region radially adjacent to the receptacle, a second annular region radially adjacent to the first annular region, and a third annular region radially adjacent to the second annular region, can be produced particularly easily if the second annular region has a plurality of spokes connecting the first and the third annular regions to one another and if there are flow channels extending in the axial direction between the spokes.

摘要： A rotor of a centrifugal separator, wherein the rotor comprises a central shaft on which an axially movable plate stack, formed by multiple plates, is arranged. A stack base is arranged on the shaft under the plate stack. A stack cap is arranged in an axially moveable manner on the shaft above the plate stack. The rotor includes a compression spring surrounding the shaft, with a first end supported on the shaft and a second end supported on the stack cap, pressing the plate stack together. The rotor includes a sleeve-like extension arranged on the stack cap, projecting into the plate stack and surrounding the shaft with a separation. The compression spring is located inside the extension, at least over a majority of the axial length thereof. A support surface for the second end of the compression spring, is arranged on a base of the extension.

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： 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 fluid filter mountable on a connection flange having a central stand pipe, and having 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, wherein the second arrangement interacts in a centering manner with the screw housing free edge when installed.

摘要： A filter comprising a filter housing, a removable housing cover closing the housing during operation, a liquid inlet, a filtered liquid outlet, an exchangeable filter cartridge separating a raw side of the filter from a clean side, and a filter bypass valve comprising a valve seat and a valve body movably guided relative to the valve seat and biased in a closed direction. The valve seat is fixed in or on the housing cover, the valve body and a spring pre-loading the valve body in the closed direction are guided in or on the housing cover and are fixed to the cover. The filter cartridge has a spring support, such that when the cartridge is installed in the filter and the housing cover is attached to the housing, the end of the spring facing away from the valve body is supported and pre-stressed via the spring support.

摘要： The invention relates to a filter cartridge for insertion in a filter housing of a fluid filter, comprising: a filter material configured to filter a fluid flowing therethrough from a raw side to a clean side of the fluid filter during operation of the fluid filter; and a filter-cartridge-side radio module configured to move, during operation of the fluid filter, according to the pressure difference between the raw side and the clean side of the fluid filter, which pressure difference depends on the degree of contamination of the filter material, and to communicate, in order to ascertain the degree of contamination of the filter material, with a housing-side radio module of the fluid filter, the distance (A) of which housing-side radio module from the filter-cartridge-side radio module varies upon movement of the filter-cartridge-side radio module.
