Embodiment Construction

[0035] Figures 1 to 12 An assembly for an exhaust system of an internal combustion engine is shown, comprising a valve 1 , an actuator 2 , an inlet flange 4 and an outlet flange 6 . The inflow flange 4 includes two conduits 8, 9, which are separated by a spacer 10 in the inflow flange 4; see for details Figure 5 . A pipe can be welded to the inflow flange 4 at each conduit 8 , 9 in a manner not shown in detail. The internal combustion engine (not shown) may have, for example, six cylinders. Exhaust gases from a first group of cylinders (eg cylinders 1 to 3 ) can be fed to a first conduit 8 which flows into flange 4 . Exhaust gas from a second group comprising, for example, cylinders 4 to 6 can be fed to a second conduit 9 which flows into flange 4 .

[0036] The valve 1 is a flap-type exhaust gas recirculation valve and comprises a housing 12 with a channel 14 through which the exhaust gas can flow in flow direction A; see in detail Figure 12 . A closing body 16 is ar...

Abstract

The invention relates to a valve (1) for an exhaust system of an internal combustion engine. The valve has the following characteristics: a housing (12) which contains a passage (14) for guiding exhaust gases; a closing body (16) is arranged in the passage (14), with which the passage (14) can be closed; the closing body (16) is fixed in a rotationally fixed manner to a shaft (18) rotatably mounted in the housing and can be pivoted with the shaft (18) around the rotation axis (19) of the shaft (18); the closing body (16) has a partition wall (26) with a circular outer contour which is perpendicular to the rotation axis (19) of the shaft (18) and is separated from the housing (12) and divides the passage (14) into a first channel (28) and a second channel (29) separated from the first channel (28). The closing body (16) has a closed position in which both channels (28, 29) are closed.

Description

technical field [0001] The invention relates to a valve for an exhaust system of an internal combustion engine, in particular an exhaust gas recirculation valve, which has a housing comprising a channel for guiding the exhaust gas, a closing body arranged in the channel, using the closing The body can close the channel. Background technique [0002] Exhaust gas recirculation valves are known due to their widespread use in practice and have a duct for guiding the exhaust gas and a closing body which is arranged in the duct and has a closed position in which the closing body Close the duct and shut off the exhaust gas flow. These valves are suitable for controlling one (1) exhaust flow only. [0003] In internal combustion engines having a plurality of cylinders, in particular six or more cylinders, it can be advantageous to direct the exhaust gas flow of a first group of cylinders having a first exhaust manifold into a first conduit and through a second The second exhaust ...
