DETAILED DESCRIPTION

(8) FIG. 1 shows an assembly 10. The assembly 10 may be mounted in a motor vehicle which is not illustrated for the sake of simplicity.

(9) The assembly 10 includes an exhaust gas-carrying pipe 12, through which exhaust gases can flow from an internal combustion engine to an exhaust.

(10) An exhaust gas recirculation component 14 via which exhaust gas can be recirculated into an intake chamber branches off from the exhaust gas-carrying pipe 12.

(11) Furthermore, the assembly 10 has a heat exchanger 16 in which heat can be transferred from the exhaust gas flowing through the exhaust gas-carrying pipe 12 to a heat-transfer medium, hereinafter referred to as a coolant.

(12) To this end, the heat exchanger 16 includes a coolant jacket 18 having a coolant inlet 20 and a coolant outlet 22.

(13) An adjustable element 24 which serves to control the exhaust gas flow through the exhaust gas-carrying pipe 12 is arranged in the exhaust gas-carrying pipe 12. The adjustable element 24 is a flap, for example.

(14) The adjustable element 24 is not visible in the figures, the position of the adjustable element 24 in the exhaust gas-carrying tube is however schematically drawn in FIG. 2.

(15) An actuator 26 is present for adjusting the adjustable element 24.

(16) The actuator 26 is connected to the adjustable element 24 via a rotatably mounted shank 28. The shank 28 may be formed integrally with the adjustable element 24.

(17) The position of the shank 28 is shown in FIG. 3. Though the latter shows a different embodiment than FIGS. 1 and 2, the shank 28 is arranged in an identical manner in the different embodiments.

(18) As shown in FIG. 3, the shank 28 extends through the coolant jacket 18. A sealing may be present where the shank 28 enters the coolant jacket 18 or exits the coolant jacket 18 to seal the coolant jacket 18.

(19) The actuator 26 is connected in a planar manner to the coolant jacket 18 via a connecting surface 30. The connecting surface 30 does not necessarily have to be provided on the coolant jacket 18, it is also conceivable that the actuator 26 is connected to another part of the vehicle structure.

(20) A housing 34 of the actuator 26 rests directly against the connecting surface 30 and is connected thereto by an intermaterial bond, in particular soldered or glued. Within the meaning of the present application, the term direct contact is also used when there is a small distance between the actuator 26 and the connecting surface 30 due to an adhesive or solder layer. Such an adhesive layer or solder layer is shown schematically in FIG. 2.

(21) The adhesive or solder can be applied over the entire surface. Alternatively, a large number of individual, separate adhesive dots or solder dots can be distributed evenly over the connecting surface 30 at a small distance from each other.

(22) The connecting surface 30 is preferably configured to be flat. However, more complex, for example single or multiple curved or stepped connecting surfaces 30 are also conceivable.

(23) The connecting surface 30 may be configured to be continuous or interrupted. That is, there may be two connecting surfaces 30 separate from each other.

(24) In the embodiment shown in FIG. 3, an intermediate plate 32 is arranged between the coolant jacket 18 and the actuator 26.

(25) The intermediate plate 32 has a lower side which rests directly against the coolant jacket 18, more specifically against the connecting surface 30, and an upper side which rests against the housing 34 of the actuator 26.

(26) The intermediate plate 32 can be stepped as shown, such that the upper side against which the actuator 26 rests is larger than the lower side which rests against the connecting surface 30. In this way, the largest possible contact surface can be provided for the actuator 26 even if the connecting surface 30 is limited due to installation space conditions.

(27) The intermediate plate 32 is, for example, connected to the connecting surface 30 by an intermaterial bond, in particular glued or soldered. The entire lower side of the intermediate plate 32 may be covered with adhesive or solder.

(28) The actuator 26 may also be glued or soldered to the intermediate plate 32.

(29) For example, a recess 36 is provided in the connecting surface 30, in particular in the region where the shank 28 extends through the coolant jacket 18. The recess 36 can be seen in FIG. 4, which shows a top view of the intermediate plate 32.

(30) A recess is also provided in the intermediate plate 32 in the region of the shank 28.

(31) In a further embodiment shown in FIG. 5, the connecting surface 30 may be of smaller design than in the embodiment shown in FIG. 3, such that no gluing or soldering is provided in a region around the shank 28. That is, the lower side of the intermediate plate 32 is only partially covered with adhesive or solder.

(32) FIG. 6 shows a further embodiment. According to FIG. 6, the connecting surface 30 does not run in one plane, but on different planes. In particular, the vehicle structure, in the example embodiment the coolant jacket 18, has a plurality of projections 38 extending towards the actuator 26. The connecting surface 30 extends, on the one hand, along the end faces 40 of the projections 38 and, on the other hand, on a surface offset from the end faces 40.

(33) In a further embodiment, the connecting surface 30 may extend over all side surfaces of a respective projection 38.

(34) Although various embodiments have been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this disclosure. For that reason, the following claims should be studied to determine the true scope and content of this disclosure.
