    摘要： An intake pipe (10) for an internal combustion engine composed of shells (11a, 11b) in which the geometry of the joining surfaces (19) 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 (16) 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 (11a, 11b) 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.

    摘要： A switching assembly (10) having closure elements such as switch valves (18), for example, for closing intake lines (24b) and an intake manifold (28) in which the switching assembly is installed. The switching assembly (10) advantageously is composed of assembly injection-molded valve modules including switch valves (18) and a frame (14b). Alternatively, the switch valves (18) may also be injection molded directly in place in the support component (17). Because it may be pre-assembled, the entire switching assembly (10) may be easily installed in the intake manifold. In addition, the switching assembly preferably has rotational axes (15) which lie at a right angle to the alignment of the valves. It is advantageous that each switch valve (18) 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.

    摘要： An intake manifold (10) for a multi-cylinder internal combustion engine includes a tubular intake distributor (12) from which a plurality of long intake tubes (13) extend and lead to the individual cylinders. Short intake tubes (14) likewise extend from the intake distributor and open into the respective associated long intake tubes (13). The intake distributor (12) and the long and short intake tubes (13, 14) are formed from a one-piece housing (11) which has a cavity (21) which intersects the short intake tubes (14). In this cavity (21) a control element (15) is installed, which includes flaps (16), flap frames (17), a shaft (19) and a control element frame (18). By moving the shaft (19) either rotationally or translationally, the short intake tubes (14) can be opened or closed. In contrast to arrangements known in the prior art, the control element (15) has no sealing elements which can catch or jam during assembly. Additionally, the arrangement of the flaps (16) on a continuous shaft (19) provides a space-saving apparatus.

    摘要： 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.

    摘要： An air intake, especially for internal combustion engines with a V-shaped cylinder arrangement, which is composed of two units (16a, 16b). From the two units (16a, 16b) extend the intake ducts (19a, 19b), each associated with one cylinder bank (11) of the internal combustion engine. By dividing the air intake device into two units (16a, 16b), the unit (16a) can be mounted first on the internal combustion engine, a free space (20) for the mounting tool being necessary. Then the unit (16b) is placed and bolted on, the air intake ducts (19b) being able to run through the free space (20) in the hatched area (23), since the unit (16a) is already installed. The advantage of this air intake tube configuration is a substantially greater geometric freedom of design.

    摘要： An intake manifold with an integrated exhaust gas recirculation system (16, 17a, 17b) which is located primarily within a plenum (12) of the intake manifold and is spaced at a distance (a) from the walls (20) of the intake manifold. This limits the heat transfer to the housing of the intake manifold, so that the housing may be manufactured, for example, of synthetic resin material. Further relief of the synthetic resin housing, particularly of the intake channels (14), from thermal stress is provided in that the intake air within the plenum cools the exhaust gas in the exhaust lines (17a, b), so that the intake-air/exhaust-gas mixture within the intake channels (14) does not exceed the critical temperature for the. synthetic resin walls (20) of the channels even if the exhaust gas recirculation rates are high.
