Abstract
A shut-off member for a turbocharger for an internal combustion engine includes a first channel, a second channel, and a wall that separates the first channel from the second channel. A shut-off member opening is formed in the wall that connects the first channel and the second channel. The shut-off member opening is selectively openable and closable by a shut-off member body. A cooling channel is disposed in the wall and at least partially surrounds the shut-off member opening.
Claims8
A shut-off member for a turbocharger of an internal combustion engine, comprising:
- a first channel;
- a second channel;
- a wall, wherein the wall separates the first channel from the second channel;
- a shut-off member opening defined by the wall, wherein the shut-off member opening connects the first channel and the second channel;
- a shut-off member body, wherein the shut-off member opening is selectively openable and closable by the shut-off member body and wherein the shut-off member body is displaceable in a direction perpendicular to a direction of flow of respective exhaust gases in the first channel and the second channel;
- and
- a cooling channel, wherein the cooling channel is disposed at a location in the wall that defines the shut-off member opening and completely surrounds the shut-off member opening in a closed ring-shaped manner to cool the wall such that the shut-off member opening is not deformed;
- wherein an inlet of the first channel is disposed upstream of the shut-off member opening with respect to the direction of flow and is connected via a first manifold to first exhaust gas outlets of the internal combustion engine and wherein an outlet of the first channel is disposed downstream of the shut-off member opening with respect to the direction of flow and leads to a turbine;
- wherein an inlet of the second channel is disposed upstream of the shut-off member opening with respect to the direction of flow and is connected via a second manifold to second exhaust gas outlets of the internal combustion engine and wherein an outlet of the second channel is disposed downstream of the shut-off member opening with respect to the direction of flow and leads to the turbine.
