Abstract Outlet and inlet conduits of an internal combustion engine are united in, and carry a housing enclosing a rotor spool having one turbine and one compressor wheel. A cavity in the housing, the longitudinal axis of which is substantially parallel to a middle plane through the row of engine cylinders is adapted to receive the casing of the turbocharger, and may be designed in such a manner that the casing may be slid into the housing in the axial directions, without the housing having to be removed from the engine. Alternatively, the outlet and the inlet conduits may each, per se, be collected and form one half of the housing. The halves are brought together over the rotor spool, from both ends thereof. Resilient sealing members are preferably fitted between the two halves of the housing. A second exhaust gas turbine may be connected to the exhaust conduit from the supercharger, and may be adapted to drive at the power take-off shaft of the engine, or to drive some auxiliary.
In a turbocharging device for a multi-cylinder internal combustion engine: (A) conduits for communicating with inlet and outlet openings at cylinders of said engine and brought together so as to merge into and carry a turbine and compressor housing formed as a unitary body and enclosing a cylindrical cavity with the longitudinal axis thereof substantially parallel to a longitudinal middle plane through said cylinders, said housing being integral with said conduits, (B) said cavity having an axially directed inlet and outlet and being fully accessible from one of its ends, (C) a compressor and a turbine mounted upon a common shaft as an integral unit, and (D) a cylindrical casing enclosing said unit adapted to be slid into said cavity through said open end thereof and having passages which in mounted position fit against said inlet and outlet conduits at their merging into said housing.
