    Abstract: A filter system for liquid media has a filter housing with housing pot and housing cover. The housing pot has a drainage channel with bottom-side drainage opening. A bottom end disk of a filter element has a closure element arranged off-center to a longitudinal filter element axis. The closure element, in predetermined installation position of the filter element, extends seal-tightly across or into the drainage opening. The bottom end disk has a cutout corresponding with a positioning aid of the housing pot. By screwing on the housing cover, the filter element moves with the housing cover axially toward the drainage opening and rotates until positioning aid and cutout engage and lock the filter element relative to the housing pot in a predetermined rotational position where the closure element is axially aligned with the drainage opening.

  • Patent number: 11268908
    Abstract: 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.
