ABSTRACT:
The twin exhaust-gas-powered turbines (9, 10) driving intake air compressors (1, 2) for an internal-combustion engine are connected together and mounted on central support brackets (47, 48) by a common turbine discharge housing (20) that deflects the discharge of each turbine separately towards an outlet funnel (24) with the help of a guiding structure that contains a median wall (33). Diffuser horns (31, 32) and hollow central plugs provide, in a short axial distance, for establishing a static pressure for causing the gas to flow with uniform pressure distribution out through the discharge funnel (24). The latter portion of the outflow path is enlarged by side pieces (26, 27) fitting over holes in the central piece (20) of the discharge casing through which the diffuser horns (31, 32) protrude with ample spacing from other components. The static pressure just mentioned creates a back pressure that improves the efficiency of the turbo-superchargers in their extraction of dynamic energy from the exhaust gas stream. The air compressors are provided with a "floating" suspension from brackets (49, 50) that is tolerant of thermal expansion.
