The invention relates to a device for regulating the intake air of an internal combustion engine, comprising a sealing system for a pressure box and an opening (42) on said pressure box (41). A mobile mechanical part (43) can be introduced into the pressure box (41) through said opening (42), the sealing system sealing the pressure box (41) in relation to the mobile mechanical part (43). Said sealing system consists of a plastic friction bearing (45) which rests on the mobile part (43) over a predetermined length and which is rigidly anchored in the opening (42) of the pressure box (41) by means of the sealing system. A Teflon ring (46) is arranged in the sealing system at one end of the plastic friction bearing (45), surrounding the mobile part (43) in such a way that it is pressure-tight.

The invention relates to a flap mechanism which comprises means for compensating tolerances and the shrinkage behavior of the flap (11). These means exist primarily by the provision of a flap edge (14) which is connected by injection molding after the injection molded flap (11) has cooled, and thus reduces the gap between the flap (11) and the flap frame (10), said gap being produced by the shrinkage of the flap. In addition, the mounting of the shaft (12) in the frame (10) can be realized in an at least partially conical manner, whereby the shrinkage behavior of the flap shaft can be used, especially in an axial direction, in order to produce a mounting which is free of play. As a result, it is no longer necessary to use additional sealing elements on the mounting points of the flap. In addition, the flap is prevented from vibrating in the mounting which, in the worst case scenario, could lead to a destruction of the flap.

The invention relates to a device for moving a valve flap, especially in the intake system of an internal combustion engine. The inventive device consists of a vacuum cell (20) which performs a lengthways movement in dependence on the application of a negative pressure. Said lengthways movement is transmitted to a cross-member (15) via a coupling rod (16). Said cross-member (15) is connected to a lever of the valve flap (11). The coupling rod and cross-member system allows the vacuum cell to be arranged in any position in relation to the valve flap (11). The invention can be simplified further by amalgamating the diaphragm disk (27) with the cross-member (15) so that they form a single integral part. In this case, a force is exerted excentrically on the vacuum cell. Said force can be compensated by the diaphragm having a shape other than a round contour.

The invention concerns an intake module (11) for an internal combustion engine, said intake module (11) comprising additional intake ducts (12) which can be closed by flaps (13). These flaps (13) are connected to one another via coupling means and to actuating means in the form of a servomotor. In order to compensate tolerances between the flaps and actuating means, the coupling means have a resilient region which above all allows the intake ducts to be closed and opened completely. The resilience can be brought about by a change in cross-section or material reduction (20). In one variant of the invention, the coupling means are composed of multipart articulated main rods (17) which control the flaps (13) by means of resiliently mounted legs (19). In another variant, the coupling means are designed as a main rod (17) with branch rods (35) emerging therefrom, the resilient region extending as a relatively thin cross-section of the branch rods over their entire length.

The invention relates to a system for recirculating exhaust gas in an internal combustion engine. A connecting line (4; 10, 13; 26) for the recirculated exhaust gas is connected to an intake pipe (2; 15; 22), cooling elements being arranged in between. The cooling element may be e.g., a cooling channel (5; 18; 19; 25) for liquid coolant, integrated into the flange-type connection joining the connecting line (4; 10, 13; 26) to the intake pipe (2; 15; 22), or may be another heat conductive element.

A suction pipe unit (10) for a multi-cylinder internal combustion engine has a pipe-shaped intake distributor (12) at least long suction pipes (13) extending from said distributor and leading to the individual cylinders. Short suction pipes (14) also extend from the distributor (12) and lead into the corresponding long suction pipe (13). The intake distributor (12) and the long and short suction pipes (13, 14) are made from a single-component housing (11), one of which has an opening (21) which cuts through the short suction pipe (14). A switch (15) is housed in said opening (21). Said switch has butterfly valves (16), a valve holder (17), an axle (19) and a switch holder (18). Rotation of the axle (19) opens or closes of the short suction pipe (14). The switch (15), in contrast to the prior art, does not have seals which can jam during assembly. A space saving solution is provided by placement of the butterfly valves (16) on the universal axis (19).

The invention relates to an air-routing system, especially a suction system of an internal combustion engine. The inventive system makes optimal use of the available installation space by integrating a bypass channel (25) into the suction module. The volume of the bypass channel also provides an acoustic shield for the collector chamber (22). The free screwing area (13) behind the fastening flange (11) that is required for mounting the suction module (11) is used by an air intake hood (14) which can be placed on the filter housing (15) after the suction module has been mounted. This ensures that there is a greater volume available in the filter housing (15), hereby reducing the muzzle noise on the air intake part of the suction module.

The invention relates to a drum controller which is especially used in the induction system of a multi-cylinder internal combustion engine, comprising an induction distributor and individual induction pipes arranged next to each other and ending in a flange. Said controller is arranged in a longitudinal bore hole of the individual induction pipes and is used to open and close said tubes. The drum controller (10) comprises a moveable sleeve (15) and a fixed core (16). The individual induction pipes (11) are opened or closed when said sleeve (15) is rotated.
