FILTER-VALVE FOR INTERNAL COMBUSTION ENGINES

摘要

The present invention refers to improvements and claims of a valve filter applicable to any type of internal combustion engine, which combination and means forming said filter enable to filter the combustion vapor in order to direct them to the engine intake manifold, reusing the crude gasoline which could not be combusted and providing enough ventilation to the crankcase to reduce atmospheric pollution. The valve filter of the present invention has a self cleaning system which prevents carbonization returning the lubricant to the crankcase, increasing engine power and performance.
