  • Patent number: 10480659
    Abstract: A coupling device, for the rotary coupling of a pivot shaft of a flap diaphragm of an exhaust gas flap with a drive element, includes at least one coupling element (36) with a first coupling area (40) configured for coupling to the pivot shaft (18), with a second coupling area (42) configured for coupling to the drive element (34) and with at least one connection area (52, 58) connecting the first coupling area (40) to the second coupling area (42). In the coupled state, the first coupling area (40) and the second coupling area (42) are prestressed in a direction towards one another or in a direction away from one another. The at least one coupling element (36) is formed with sheet material.

  • Patent number: 10450969
    Abstract: An electric exhaust gas valve device (1) controls a flow cross section (5) of an exhaust pipe (6) of an exhaust system (8) of an internal combustion engine. The valve device includes an electric drive (2) driving a driven shaft (9) rotatingly about an axis of rotation (10). An exhaust gas valve (3) has a drive shaft (12) aligned coaxially to and rotatable about the axis of rotation for controlling the cross section. A coupling device (4) transmits torques between the driven shaft and the drive shaft and includes a connection element connected to the drive shaft, a transmission element (16) connected to the driven shaft and the connection element with a prestressing spring (18) supported axially on the connection element and/or on the drive shaft as well as on the transmission element and axially driving the transmission element against the driven shaft to reduce thermal load.

  • Patent number: 10281048
    Abstract: A three-way flap valve (4) includes an inlet (1), a first outlet (2), a second outlet (3), and a valve flap (5). The valve flap (5) can be moved between at least a first position and a second position. In the first position of the valve flap (5), fluid flowing in through the inlet (1) is directed to the first outlet (2). In the second position of the valve flap (5), fluid flowing in through the inlet (1) is directed to the second outlet (3). A surface (51) of the valve flap (5) circumscribed by an outer edge (53) includes at least a first surface section (A1), where the surface of the valve flap (5) has a curvature.

  • Patent number: 9709350
    Abstract: A heat exchanger (5) includes a housing (31), which contains a tube (32) and has a jacket (33), which surrounds the tube (32) while forming a ring channel (34). A primary inlet (35) and a primary outlet (36) are connected to one another fluidically via a primary path (37) carrying a primary medium through ring channel (34) and via a bypass path (38) carrying the primary medium through the tube (32). A control device (39) controls the flow of the primary medium through the primary path (37) and the bypass path (38). A secondary inlet (42) and a secondary outlet (43) are connected to one another fluidically via at least two secondary paths (44) for carrying a secondary medium. The primary path (37) is coupled with the secondary paths (44) in a heat-transferring manner with the media separated from one another.

  • Patent number: 9239001
    Abstract: A heat exchanger (28) has a first inlet (29) and a first outlet (30), which are fluidically connected with one another via a first path (31) carrying for a first medium to be cooled. A second inlet (32) and a second outlet (33) are fluidically connected with one another via a second path (34) carrying a second medium. A third inlet (35) and a third outlet (36) are fluidically connected with one another via a third path (37) carrying a third medium. The first path (31) is coupled with the second path (34) and with the third path (37) in a heat-transferring manner and in such as way that the media are separated. The heat-transferring coupling between the first path and the second path takes place upstream of the heat-transferring coupling between the first path and the third path relative to the direction of flow of the first medium.
