  • Crankcase emission control system
    Patent number: 5564401
    Abstract: A closed crankcase emission control assembly for an internal combustion engine incorporates into a single compact unit a pressure control assembly, a filter and an oil drain check valve. The pressure control assembly has a gate whereon oily contaminated crankcase emission impinge and oil is separated. The separated oil is collected in a reservoir and returned to the crankcase. The pressure control assembly also has a variable orifice agglomerator which agglomerates particles in the contaminated crankcase emission to form larger particles. Thus, the pressure control assembly simultaneously regulates pressure, separates oil and agglomerates particles. The agglomerated particles are filtered by a filter which may be coarse and clogs less often.
