  • Patent number: 9999843
    Abstract: An apparatus, system and method are provided for controlling fluid flow through a vacuum chamber of a dehydration system, the vacuum chamber having a temperature sensing device operative to measure a temperature of a fluid in the vacuum chamber. A temperature difference between a temperature setpoint for the fluid and the measured temperature of the fluid is determined, and fluid is recirculated through the vacuum chamber while the temperature difference is greater than a predetermined temperature difference. While the temperature difference is less than the predetermined temperature difference, the fluid is recirculated through the vacuum chamber for a predetermined time period, and upon the predetermined time period expiring inhibiting recirculation of the fluid through the vacuum chamber.
    Type: Grant

  • Patent number: 9010365
    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.
