Engine cooling flow debris cleaner and air pre-cleaner aspirator

摘要

A work vehicle (10) operating in a highly contaminated environment has a radiator (28) with a rotary screen debris removal device (40) upstream of the radiator (28). The debris thus removed passes through a fan (56) for disposal away from the work machine (10). The engine (10) is an air breathing fuel consuming engine and has a pre-cleaner (20) for removing larger particles of air delivered to the engine (14) for combustion. A particle conduit (26) extends from the intake air pre-cleaner (20) to a venturi device (50) adjacent to and upstream of the fan (56) for continuously and effectively removing particles from the engine air pre-cleaner (20).
