ABSTRACT:
An oil sparator for a blowby gas ventilation system of an internal combustion engine which includes a cylinder head cover, a baffle plate, a blowby gas path formed between the cylinder head cover and the baffle plate, and a filter provided in the blowby gas path. A groove is formed in the baffle plate and extends along the filter over the entire width of a top wall of the baffle plate. The filtered oil collects in the groove and does not appear on the upper surface of the top wall of the baffle plate. Therefore, the collected oil in the groove does not flow through the filter together with the blowby gas. As a result, oil consumption is decreased and oil blow-out through a blowby gas outlet is prevented.
