Open the CIPO recordAbstract From the Canadian patent
In a device for separating oil from the blow-by exhaust vapors of a combustion engine, a filter stack is mounted in a canister having an inlet port for the intake of said vapors from the engine, a gas outlet port for connection to a source of suction for causing the vapors to flow through the canister and, a discharge port communicating with said flow passage for removal of condensed oil. The filter stack is operatively arranged so that the vapors pass in contact with and through the filter stack. A plate partially surrounds the filter so that the oil in the vapors condense, and flow outwardly through the passage between the plate and the interior wall surface of the canister.

Why it's free to use
- Filed November 29, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 29, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 29, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
