Patent ID: 8113182

Claim:
Integrated supercharger module comprising a low-pressure charging device ( 2 ) having a low-pressure compressor housing ( 4 ), a high-pressure charging device ( 3 ) having a high-pressure compressor housing ( 5 ), a turbine ( 9 ) and a cooler arrangement comprising an intermediate cooler ( 1 ) and a high-pressure cooler ( 6 ), wherein the intermediate cooler ( 1 ) is between the low-pressure charging device ( 2 ) and the high-pressure charging device ( 3 ), wherein the low-pressure charging device ( 2 ), the high-pressure charging device ( 3 ), the turbine ( 9 ) and the cooler arrangement form a structural unit, wherein the low-pressure charging device ( 2 ), the high-pressure charging device ( 3 ) and the turbine ( 9 ) have a common axis of rotation, wherein a centre of an inlet to the low-pressure charging device ( 2 ) and a centre of an outlet from the high-pressure cooler ( 6 ) are along a common supercharger module axis, wherein an axis of the intermediate cooler ( 1 ) is parallel to the common supercharger module axis, and wherein at least one of the low-pressure compressor housing ( 4 ) and the high-pressure compressor housing ( 5 ) has an axial inlet and a radial outlet.
