Abstract
An oil mist eliminator filter used with a dynamic oil control mechanism consisting of a vacuum-inducing jet-pump to vacuum oil leaking from about an oil seal, an oil seal located around the drive piston on the press slide, a drain port located about the housing in which the drive piston reciprocates. The oil mist eliminator filter, downstream of the jet pump, separates the oil from the air with 99.97% efficiency allowing the cleaned air to escape freely to atmosphere without causing pressurization of the press reservoir and leaks at the press reservoir, and allowing the oil to constantly recirculate back to the press reservoir thus permitting use of the oil control system without the need to shut the oil control system off to drain accumulated leakage oil.
