    摘要: A round filter element of a filter for a urea-water solution has a filter bellows with a filter medium that continuously extends circumferentially, relative to a filter element axis, around an element interior. An end body is fastened to an end face of the filter bellows and provided with a connecting section for fastening the round filter element to a housing cover of a filter housing of the filter. The end body has a central opening communicating with the element interior. The central opening has a central insertion section for receiving a flexible separation section of a volume compensation device of the filter and has an outer flow-through section enabling flow of the urea-water solution out of the filtration volume or into the filtration volume. The filter has a volume compensation device with a flexible separation section that separates a compensation volume from the filtration volume of the filter.

    摘要: A filter system (100) having a housing (110), a fluid inlet (102) formed in a housing wall (112), a fluid outlet (108) formed in a housing wall (120), a primary filter element (50) and a secondary filter element (10). The secondary filter element (10) is arranged on a stand pipe (150) which is rigidly connected to one of the housing walls (120). The secondary filter element (10) comprises a filter medium (16) forming a body (36) having at least one longitudinal seam (18) along a longitudinal axis (L). The filter body (36) has a first edge (13) at one region (12) which is curved in an initial unwound state of the filter medium (16) and straight in a final wound state of the filter medium (16) forming the filter body (36) and a second edge (15) at the opposite region (14) of the filter body (36) with respect to the longitudinal axis (L) which is straight in an initial unwound state of the filter medium (16) and curved in a final wound state of the filter medium (16) forming the filter body (36). A method of manufacturing is also disclosed.

    摘要: The invention relates to a fluid pipe arrangement (100), in particular for a charged air duct of an internal combustion engine, comprising a housing (10) having a longitudinal extension (L). The housing (10) includes a first fluid duct (20) having a first fluid inlet (22) and a first fluid outlet (24) for a first fluid and at least one second fluid duct (30) having a second fluid inlet (32) and a second fluid outlet (34) for a second fluid. Thermal insulation means (40) are provided between at least a portion (38) of the second fluid duct (30) and at least a portion (28) the first fluid duct (20).

    摘要: An air dryer cartridge for reducing moisture of air supplied to an electronics housing has a cartridge housing containing a drying agent through which air is guided. A sensor unit of an optical measuring system is provided for determining the moisture content of the drying agent. The cartridge has a light-permeable casing surface section so that an optical signal emitted from the optical measuring system can pass through the casing surface section. In the method for determining a moisture content of the drying agent of the air dryer cartridge, an optical signal from a sending module is emitted onto or through the drying agent and received by a receiving module where a measured value is determined. The moisture content is determined by comparing the measured value with a data set of measured value-specific values for moisture contents or by a calculation rule for moisture content based on measured value.

    摘要: The invention relates to a filter element (1, 31) for use as a particulate filter in a cooling circuit (100), in particular of an electrochemical energy converter, having a conical grid support structure (3, 33). The filter element features at a first axial end a supply opening (23, 49) for supplying a cooling medium to be filtered into the filter element (1, 31) and the grid support structure (3, 33) carries a filter medium (4, 34). The filter element (1, 31) has axially opposite the supply opening (23, 49) a funnel (16, 40) for axially discharging and collecting particulate impurities, and is closed at second axial end. The conical grid support (3, 33) structure tapers from the first axial end to the second axial end. An arrangement of a fuel cell (102) having a a cooling circuit (100) with the filter element is disclosed.

    摘要: A separating device for separating a liquid from gas is provided with a separating element that has a housing with housing cover closing off an end face of the housing. A filter element is arranged in the housing. A coupling element is provided to couple the separating element to a connector device. The housing cover has a central first gas passage and a second gas passage arranged radially outwardly of the first gas passage. The housing cover has a housing cover thread correlated with the first gas passage. The housing cover thread is to be screwed to a coupling element thread of the coupling element. A fluid discharge channel is arranged within the coupling element for discharging separated liquid from the separating device. The housing cover thread and the coupling element thread, in a position of use of the separating device, are connected substantially seal-tightly to each other.
