  • Publication number: 20220025979
    Abstract: A valve body for a valve has an envelope surface with a bell-shaped cross section contour in a longitudinal direction of the valve body. The envelope surface is provided with a guide region for guiding the valve body in a valve seat and is further provided with a sealing region for contacting fluid-tightly the valve seat. The sealing region adjoins in the longitudinal direction the guide region. The bell-shaped cross section contour in the longitudinal direction from the guide region to the sealing region is open at one side and increases strictly monotonously. The valve body is formed of a thermoplastic polyhalogen olefin. A crankcase ventilation device is provided that is provided with a valve provided with such a valve body.

  • Publication number: 20220016567
    Abstract: A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.

  • Publication number: 20210363902
    Abstract: A valve has a valve housing with a valve seat and a valve body holder with a fluid-permeable flow opening. A valve body is arranged in the valve body holder and axially displaceable between an open state and a closed state of the valve. The valve body has an envelope surface with a sealing region for fluid-tightly contacting the valve seat in the closed state. It has a base region adjoining the sealing region in longitudinal direction. A cross section contour of the envelope surface increases monotonously from the sealing region to the base region. In the open state, an axial end of the base region contacts the valve body holder. The envelope surface has a weakened region connecting sealing region and base region to each other. The weakened region has a reduced stiffness along the longitudinal direction. The valve body is formed of a thermoplastic polyhalogen olefin.

  • Patent number: 10632412
    Abstract: A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.
