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.

A pressure equalization device for a housing has a base body and a closure element with a flow path between them being open in a normal operating state of the pressure equalization device. A flow opening in the flow path is spanned by a membrane. An emergency venting spike projects from the closure element toward the membrane. The pressure equalization device transitions after emergency venting into an emergency operating state in which the closure element gas-tightly closes the base body. A housing with such a pressure equalization device is provided. In a method for pressure equalization with such a pressure equalization device between a housing interior and an environment, gas exchange between interior and environment is performed through the membrane and the flow path between closure element and base body. During emergency venting, the membrane is destroyed by the emergency venting spike. The closure element then closes the base body.

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.

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.

A brake dust particle filter for a disc brake assembly is provided to catch particles generated during braking. The brake dust particle filter has a ring segment-shaped housing with two axially spaced apart housing side walls and a radially outwardly positioned housing peripheral wall. The housing peripheral wall is arranged between the housing side walls. The housing accommodates the brake disc in the housing interior. A tongue projects inwardly away from the housing peripheral wall in the housing interior. The tongue projects at least in sections with a radial component and has a flat cross section with a base surface facing the housing peripheral wall, an end face projecting into the housing interior, and a side face. The tongue is formed by a filter medium and has no supporting device components separate from the filter medium. The filter medium provides a satisfactory stiffness keeping the tongue structurally stiff.

A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

A unit for the regulation for control of a fluid pressure, having at least one housing section and a switching film connected to the at least one housing section. A chemically inert, non-rubber-like PTFEswitching film switching film is disposed in the valve housing and switches at pressure differences of 1 mbar to 250 mbar for regulating, opening or blocking a flow of a fluid from the inlet to the outlet. The switching film is formed of a fluorine and carbon containing polymer material. The switching film has a plate-shaped flat body with a bending region and has a central closure region surrounded by the bending region. The bending region, when switching the switching film, moves the central closure region relative to a valve seat of the valve housing in an axial direction of the plate-shaped flat body toward or away from the valve seat by a stretch free or low-stretch bending movement.
