  • Patent number: 11920547
    Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore, a valve body received at least in sections in the valve bore, an actuation rod for actuating the valve body, and a coupling device operatively connecting the actuation rod with the valve body and enabling a tilting of the actuation rod in relation to the valve body. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to the valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and in reverse. The filter module has a filter housing with a housing top part. The valve body, upon transfer of the water drainage device from closed state into open state, moves toward the housing top part of the filter housing.

  • Patent number: 11811085
    Abstract: A degassing unit for an electronics housing has a base body with gas passage opening and is connectable fluid-tightly to a rim of a pressure compensation opening of the electronics housing. A semipermeable membrane for covering the pressure compensation opening enables passage of gaseous media from an environment into the electronics housing interior and vice versa but prevents passage of liquids and solids. A membrane support device, arranged at an interior side of the base body facing the electronics housing interior, engages across the gas passage opening and is positioned at a first distance to the semipermeable membrane. A separation lattice with lattice openings is arranged at the interior side of the base body at a second larger distance to the semipermeable membrane and completely engages across the gas passage opening. A surface area spanned by the separation lattice is larger than a cross section of the gas passage opening.

  • Patent number: 11804633
    Abstract: A degassing unit to be connected fluid-tightly to a pressure compensation opening of an electronics housing has a base body with gas passage opening. A semipermeable membrane, fastened fluid-tightly to a membrane carrier, allows gaseous media to pass from an environment into the electronics housing and in reverse but prevents passage of liquid media and solids. In normal operation, the membrane covers the gas passage opening. An axial seal circumferentially extends about the gas passage opening. The membrane carrier is moveable relative to the base body and, in normal operation, is pressed by axial force seal-tightly against the axial seal. The membrane carrier, when a predetermined pressure difference between housing interior and environment is surpassed, lifts off the base body to release an emergency degassing opening surrounding the membrane. The axial seal is a lip seal and made of a material softer than a material of the membrane carrier.
