Monoblock and rigid coupling for coupling turbocompressor in e.g. diesel engine, has successive elbows defining intermediate sector between intermediate portions, where radii of curvature of elbows are contained in three distinct planes

摘要

The coupling (50) has an burnt gas inlet duct (51) connected to burnt gas outlet duct (53) by bent intermediate sector, where the inlet duct extends along an inlet axis (A1) and the outlet duct extends along an outlet axis (A4). Three successive elbows (54-56) define the intermediate sector between intermediate portions (52a, 52b), where radii of curvature (R1-R3) of the elbows are contained in three distinct planes. The portions of the intermediate sector are orthogonal to the inlet and outlet ducts. The ducts are realized by bending a steel tube. An independent claim is also included for an internal combustion engine, comprising fresh gas intake line emerging into cylinders of an engine block.
