Abstract
The invention relates to an oil separator (1) for de-oiling crankcase ventilation gases of an internal combustion engine with the oil separator (1) comprising a cyclone encompassing a gas inlet connected to the crankcase of the internal combustion engine, a gas outlet connected to the suction passage of the internal combustion engine, and an oil outlet connected to a crankcase sump of the internal combustion engine. The novel oil separator is characterized in that instead of a single cyclone several smaller cyclones (11, 12, 13, 14) are provided arranged in parallel with each other.
Claims21
An oil separator for de-oiling crankcase ventilation gases in an internal combustion engine, said oil separator comprising a plurality of cyclones, each communicating with a gas inlet for connection to a crankcase of an internal combustion engine and with a gas outlet for connection to a suction passage of the internal combustion engine, and each having an oil outlet for connection to a crankcase sump of the internal combustion engine, wherein said cyclones are arranged such that a gas flow therethrough occurs in parallel through said plurality of cyclones.
An oil separator for de-oiling crankcase ventilation gases in an internal combustion engine, said oil separator comprising a plurality of clones, each cyclone having a tangential gas inlet, a gas outlet, and an oil outlet at a lower end thereof, wherein a flow of ventilation gases through said oil separator occurs in parallel through said plurality of cyclones.
