Abstract: The disclosure concerns a separator for removing broken engine parts and other debris from the hot gases passing fro the exhaust manifold of an engine to the inlet of an associated turbocharger. The separator includes an annular separation chamber in which the gases are swirled by stationary vanes to effect centrifugal separation of the debris, and a cylindrical screen which filters the gases as they leave the separation chamber. The screen is mounted in cantilever fashion within the separator casing and carries, at its free end, the vanes and a deflector which directs inlet flow radially outward to the separation chamber. The vanes are freely mounted in slots formed in the screen, where they are held captive by the slot margins and the deflector, and the tips of the vanes are spaced radially from the surrounding casing of the separator.
