Abstract
A turbocharger and intake air cleaning device for use with internal combustion engines. A collection spout is mounted tangent to the volute of the diffuser housing at a position from the turbocharger's discharge port which is upstream relative to the direction of rotation of air within the housing. A nozzle is mounted in the distal end of the collection spout. Dirt and other foreign matter carried in the rotating air stream migrates by centrifugal action into the collection spout where it is separated from compressed air flowing through the discharge port. An opening in the nozzle expels the foreign matter while at the same time limiting air leakage so as to maintain boost pressure within the diffuser.
Claims5
An air cleaner and turbocharger device comprising a turbocharger housing including an inlet and enclosing a rotary impeller, said housing being a volute-shaped diffuser into which air is compressed by the impeller, said diffuser having a tangential gas discharge port, means forming a collection spout extending outwardly from the periphery of the diffuser and the gas discharge port for trapping and collecting foreign matter carried in a stream of air rotating within the diffuser, and a nozzle mounted in the discharge end of the spout, said nozzle being formed with an opening sized larger than said foreign matter for expelling the collected foreign matter from the spout, said opening being sized substantially less than the diameter of the collection spout for restricting air leakage through the nozzle for minimizing pressure loss within the diffuser and thereby maintaining boost pressure in the discharge port of the diffuser.
