Abstract
A supercharger set for internal combustion engines comprising two turboblowers the two axes of which being mutually perpendicular. The high-pressure turbine is mechanically coupled to the high-pressure compressor, whereas the low-pressure turbine is mechanically coupled to the low-pressure compressor. A single casing is used for the egress of the gases from the high-pressure turbine and their ingress into the low-pressure turbine.
Claims5
In a two-stage exhaust-gas driven supercharger set for an internal combustion engine having an inlet manifold and an exhaust manifold, the supercharger set including a high-pressure turbocompressor having a high-pressure turbine mounted on a common first shaft with a high-pressure compressor, and a low-pressure turbocompressor having a low-pressure turbine mounted on a common second shaft with a low-pressure compressor, the axes of the first and second shafts being mutually perpendicular, the inlet of the high-pressure turbine being connected to the exhaust manifold, the outlet of the high-pressure turbine being connected to the inlet of the low-pressure turbine, the outlet of the low-pressure compressor being connected in series with the inlet of the high-pressure compressor, and the outlet of the high-pressure compressor being connected in series with the inlet manifold, the improved arrangement comprising:
- a single casing directly connecting the outlet of the high-pressure turbine to the inlet of the low-pressure turbine and wherein the single casing feeds exhaust gases from a circumferential outlet of the high-pressure turbine in a straight line directly into an axial inlet of the low-pressure turbine.
