Integrated three-phase cyclonic fluid seperator and reservoir venting device

摘要

An apparatus (10) separates liquid, gas and solid components of a mixture in an engine lubricating system. An inlet (20) for receiving the mixture opens tangentially into a separation chamber (14) and a gas outlet (46) has an opening in a first end (15) wall adjacent the inlet to allow gas to exit the apparatus. A fluid outlet (24) is in an opposing second end (18) wall and opens into a lubricant reservoir (40) of the engine lubricating system. Both liquid and gas flow through the fluid outlet between the separator and the reservoir. A particle collector (33) is provided adjacent the second end (18) wall to receive solids that become separated from the mixture. A baffle (36) may be provided to direct the separated liquid from the apparatus into the reservoir (40) while allowing gas in the reservoir to flow into the separator.
