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.

Device for the combined reduction of the carbon dioxide and water or moisture content, motor vehicle, and method

A filter element has a filter medium body with a first side and an oppositely positioned second side, wherein one of the first and second sides is the inflow side of the filter medium body and the other one is the outflow side of the filter medium body. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. At least one force-transmitting adhesive bead extends between the first side and the second side, wherein the at least one adhesive bead is a force transmitting element extending between the first and second sealing or supporting elements.

Filter element, in particular for gas filtration

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.

Valve with valve body, and crankcase ventilation device

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.

A device for producing a bellows from a filter medium, including: an embossing device embossing fold lines into a filter medium that runs through the embossing device, producing an embossed filter medium for folding into a folded filter medium; the folded section of the filter medium being delimited by two adjacent fold lines; an adhesive application device applying adhesive onto the embossed filter medium; and a folding device folding, in a zig-zag manner, the embossed filter medium onto which the adhesive was applied into the folded filter medium; wherein the folding device includes a plurality of adjacent supporting elements that can be moved into or out of a folding space of the folding device; wherein the supporting elements are movable into the folding space such, that at least one folded section of the folded filter medium is contacted and supported by a respective one of the plurality of supporting element.

Apparatus and method for producing a bellows

A filter element for filtering media with a pleated filter medium is described. Each pleat () is formed by two pleated sheets which form a pleat tip () with one another on the crude side () exposed to oncoming flow. Two neighboring pleats () form a pleat base () with one another, wherein the crude side () and/or the clean side () of the filter medium has a plurality of elongated adhesive sections along at least two adhesive traces (), each having at least one adhesive section and each having at least one adhesive interruption (). The mutual spacing of the two pleated sheets in the region of the pleat tip () is between zero and two mm or the two pleated sheets are in contact with one another in the region of the pleat tip (), wherein the pleat spacing () between the two pleated sheets of a pleat pocket () amounts to at least twice the pleat spacing in the region of the pleat tipin the region of the pleat base ().

Filter element for filtering media

Disclosed is an air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element having a specific retaining geometry

A filter element, in particular a flat filter element () for installation in a filter housing of a filter for a fluid, in particular an air filter, in particular for an internal combustion engine, in particular in a motor vehicle, and a filter are described. The filter element () comprises open filter bellows () made of a filter medium (), which has an oncoming flow side () and an outgoing flow side () for the fluid to be filtered. The filter element () has at least two hand grip elements () for gripping the filter element ().
