摘要

PROBLEM TO BE SOLVED: To provide an oil separator insert provided with a high washing property and manufacturing easiness. SOLUTION: The oil separator insert 15 for a cover 10 or a housing of an internal combustion engine comprises a stem member 16 and at least one helical surface member arranged along the circumference of the stem member such that a helical channel 20 is formed by the helical surface member. The helical channel is open towards an outer enveloping surface of the helical surface member. The insert is provided for being tight-fittingly inserted into a mounting 21 in the cover or the housing, allowing blow-by gases to flow through the helical channel when being tight-fittingly inserted into the mounting. At least an outer part of the helical surface member is made substantially of an elastomer based material. COPYRIGHT: (C)2009,JPO&INPIT
