Abstract
The present invention provides an apparatus and method for filtering fluid in a breather assembly and providing uncontaminated fluid to a reservoir. The breather allows in-take fluid traveling through a first flow path to be filtered before entering the reservoir through a first directional valve. The breather also allows exhaust fluid traveling through a second flow path, separate from the first flow path, to exit through a second directional valve.
