A cover for a cylinder head of an internal combustion engine having a connecting element for attachment the cylinder head and a sealing element arranged between the cylinder head cover and the cylinder head. The connecting element is associated with a connecting area, and the sealing element is associated with a sealing area. The connecting area and the sealing area are constructed independently of each other and are spatially separated from each other, and the force vectors of the connecting force transmitted by the connecting element and the sealing force transmitted by the sealing element form an angle with each other.

An intake system for an internal combustion engine having an intake plenum and at least one intake pipe which branches off from the intake plenum and which is composed of at least two intake pipe parts that are divided longitudinally. The intake plenum together with one of the intake pipe parts forms a single integral base part. The second intake pipe part is configured as an interchangeable insert that also forms one wall shell of the intake plenum.

A switching assembly ( ) having closure elements such as switch valves ( ), for example, for closing intake lines ( ) and an intake manifold ( ) in which the switching assembly is installed. The switching assembly ( ) advantageously is composed of assembly injection-molded valve modules including switch valves ( ) and a frame ( ). Alternatively, the switch valves ( ) may also be injection molded directly in place in the support component ( ). Because it may be pre-assembled, the entire switching assembly ( ) may be easily installed in the intake manifold. In addition, the switching assembly preferably has rotational axes ( ) which lie at a right angle to the alignment of the valves. It is advantageous that each switch valve ( ) has its own rotational axis, thereby avoiding additive tolerances. In this way a part is provided which is economical to produce and which satisfies the sealing requirements for the switching assembly.

An intake pipe ( ) for an internal combustion engine composed of shells ( ) in which the geometry of the joining surfaces ( ) adopts an approximately stepped course in areas with a slight incline relative to to joining force (F). This produces areas with a greater or lesser inclination relative to a joint line ( ) indicating the average inclination of the joining surfaces. This results in areas which can be welded with a high degree of stability because of their considerable incline towards the joining force. These areas can then support areas which are less inclined towards the joining force. This allows the shells ( ) to have strongly curved joining surfaces, which increases the geometric design freedom of the intake pipe and, in particular, makes it possible to manufacture intake pipes with strongly curved intake channels constructed from just two shells.

An intake device for supplying combustion air to an internal combustion engine composed of two sealingly connected half shells ( ) which form an intake air plenum ( ), intake ducts ( ), and a cylinder head flange ( ) in which there is an insert ( ) associated with each intake duct ( ). Each insert is provided with a partition ( ) for dividing the flow into two flow cross-sections ( ). The first flow cross section ( ) is provided with a valve flap ( ), which can be opened and closed to influence the filling of combustion chambers of the internal combustion engine.

An intake manifold ( ) for a multi-cylinder internal combustion engine includes a tubular intake distributor ( ) from which a plurality of long intake tubes ( ) extend and lead to the individual cylinders. Short intake tubes ( ) likewise extend from the intake distributor and open into the respective associated long intake tubes ( ). The intake distributor ( ) and the long and short intake tubes ( ) are formed from a one-piece housing ( ) which has a cavity ( ) which intersects the short intake tubes ( ). In this cavity ( ) a control element ( ) is installed, which includes flaps ( ), flap frames ( ), a shaft ( ) and a control element frame ( ). By moving the shaft ( ) either rotationally or translationally, the short intake tubes ( ) can be opened or closed. In contrast to arrangements known in the prior art, the control element ( ) has no sealing elements which can catch or jam during assembly. Additionally, the arrangement of the flaps ( ) on a continuous shaft ( ) provides a space-saving apparatus.

An intake device for an internal combustion engine, comprising welded shells joined along a partition line, in which the partition line is provided with a region for producing inclined additional surfaces, which generate a transverse force Q due to their inclination relative to a pressure force D applied for welding the shells. This transverse force Q offsets a transverse force Q which is generated as a result of the inclination of partial regions of the partition line relative to the applied pressure force D. In this way, the transverse forces which arise during production of the intake device may be at least partially offset in the component, so that little or no forces are exerted on the molding tools, and the welding results for the intake pipe may thus be improved.
