Abstract
A two-stage supercharger for an engine having a radial high-pressure turbine and an axial low-pressure turbine. The high-pressure turbine has a spiral housing with an exhaust-gas inlet connected to an exhaust line and via which exhaust-gas flows from the engine to the high-pressure turbine. A partial flow of the exhaust-gas flows past the high-pressure turbine in a bypass unit and is adjustable by a shut-off valve. The bypass unit includes a branch line and an annular duct housing integral with the spiral housing. The branch line branches off the exhaust-gas inlet at a point where the shut-off valve is arranged and issues into a duct of the annular duct housing. The partial flow flows through the branch line into the duct and an axially arranged annular gap into an exhaust-gas duct. The partial flow merges with a main exhaust-gas flow from the high-pressure turbine and flows into the low-pressure turbine.
