An active material container for a functional housing has an air-permeable casing with an interior and an active material arranged inside the interior. One or more rim-side guide elements are arranged at the air-permeable casing and are provided to linearly slidably guide the active material container in an insertion direction in corresponding guide elements of a receptacle of the functional housing. The functional housing is preferably a battery housing.

A fluid housing of a fluid treatment system of a fluid system has a housing part of plastic material that is provided with a receiving chamber for accommodating a fluid treatment component; an installation opening, closable by a closure housing part, for installing the fluid treatment component in the receiving chamber; and a housing connecting section to connect the housing part to the closure housing part. A housing fastening section is provided with which the fluid housing can be fastened to a holding component of the fluid system. An insert is at least partially introduced into the plastic material of the housing part. The insert is provided with a reinforcement region extending with sections thereof in the housing connecting section and is further provided with fastening region extending with sections thereof in the housing fastening section. A fluid treatment system with such a fluid housing is provided.

A humidification device is provided with at least one stacked unit with water vapor-permeable membranes arranged parallel and spaced apart relative to each other. The membranes each have an edge area framed by frames. The frames are formed by a film composite of a lower film and an upper film, wherein the lower and upper films of the film composite clamp the edge area of one or more of the membranes therebetween. The lower and upper films of the film composite are fixedly connected to each other. Alternatively, the frames are formed by a thermoplastic yarn that is sewn into the edge area of one or more of the membranes, respectively, wherein the thermoplastic yarn is reshaped by heat and pressure.

Humidification device, in particular for a fuel cell

A humidification device is provided with at least one stacked unit of water vapor-permeable membranes and of support frames. The support frames are stacked on each other. The membranes each are positioned between two of the support frames, respectively, and have edges clamped between the two support frames. The membranes are arranged parallel and spaced apart relative to each other. Between the two support frames, a supply air flow path extends on a first lateral face of the membrane and, angularly displaced to the supply air flow path, an exhaust air flow path extends on a second lateral face of the membrane facing away from the first lateral face. A flow opening of the supply air flow path and a flow opening of the exhaust air flow path are delimited by the two support frames and extend parallel to a plane of the membrane clamped between them.

A vacuum unit for producing a stroke movement due to an applied vacuum. The vacuum unit includes a housing, a spring disposed in the housing, a diaphragm and a drive rod arranged on the diaphragm. The drive rod is positioned centrally on the diaphragm and is mounted in a longitudinal guide in the housing.

A shift drum ( ), especially for use in an intake manifold arrangement for a multi-cylinder internal combustion engine, having an induction distributor, long individual suction pipes ( ) that are arranged adjacent one another, and short individual suction pipes ( ) that are situated interiorly. The shift drum ( ) is arranged in a longitudinal bore ( ) which intersects at least the short individual suction pipes ( ). Shift drum ( ) is further provided with radial seals ( ) which seal the individual pipes ( ) from each other. Separate seals ( ) are provided which are fixed in position on the shift drum ( ) for sealing off long individual suction pipes ( ) from short individual suction pipes ( ) in a closed position.

A tool, especially for producing molding cores. The tool is disposed in a casting apparatus and is provided with first half-shells ( ) and second half-shells ( ). Two parting planes are provided, and two casting units are formed from the first and second half-shells. These parting planes are situated one behind the other in the direction of movement of the two casting units.

An intake module for an internal combustion engine. The intake module including at least two intake ducts which can be opened and closed by rotatable valves. The valves are connected to one another via a coupling mechanism and to a common actuating mechanism in the form of a servomotor. In order to compensate for tolerances between the valves and the actuating mechanism, the coupling mechanism includes at least one elastic portion, formed by a weakened material portion, which allows the intake valves to be closed and opened completely. The resilience of the coupling mechanism can be brought about by a change in cross-section or a material reduction. In one embodiment of the invention, the coupling mechanism includes multi-part articulated main rods which control the valves by resiliently mounted legs. In another embodiment, the coupling mechanism includes a main rod having branch rods emerging therefrom with a resilient region extending as a relatively thin cross-section of the branch rods over their entire length.
