Patent number: 7517392Abstract: The present invention comprises a breather system and a method of using the system. The assembly has a breather tube, a baffle system at least partially located within the breather tube and a drain back tube connected to the breather tube. The baffle system has a plurality of baffles designed to prevent lubricant from escaping a housing while still allowing air to pass into and out of the housing.Type: GrantFiled: April 12, 2005Date of Patent: April 14, 2009Assignee: Dana Heavy Vehicle Systems Group LLCInventors: Matthew L. Neff, Leonard P. Stoehr, Leo Wenstrup
