  • Patent number: 8603209
    Abstract: An example filter assembly prevents particles from entering a control valve and defines an airflow path between an inlet and outlet. An inlet tube extends from an inlet and defines an inlet passage into a filter housing. Openings within the inlet tube open into an interior space of a filter housing. An outer housing defines a cavity within which the filter housing is secured. The filter housing includes an open top portion that engages a cap that covers and seals the outer housing. The cap holds the filter housing to prevent movement of the filter housing.

  • Publication number: 20110067765
    Abstract: Disclosed is a drain assembly including a buoyant spherical ball (32) and a drain fitting (10) including at least one drain channel (28). The drain fitting (10) is securable at a drain location (18) wherein pressurization at the drain location (18) seals the spherical ball (32) against the drain channel (28). Further disclosed is a method of operating a drain assembly for an environmental control system (14) including locating the drain assembly at a fluid collection area (22) of the environmental control system (14). The drain assembly includes a buoyant spherical ball (32) and a drain fitting (10) including at least one drain channel (28) securable at a drain location (18). An interior (22) of the environmental control system (14) is pressurized and the spherical ball (32) is sealed to the drain fitting (10) via the pressurization of the interior (22) of the environmental control system (14).

  • Patent number: 7188488
    Abstract: The present invention provides an air generation unit (AGU) including a pressurized air source, such as an engine providing pressurized air. First and second air cycle machine (ACM) are fluidly connected to the pressurized air source for receiving the air. A heat exchanger interconnects the first and second ACMs. The heat exchanger mechanically supports the first and second ACMs by flexible isolators, which accommodates the thermo expansion of the heat exchanger through out the operation of the AGU. The heat exchanger includes a primary heat exchanger that cools the air from the air source. The ACMs each include a compressor receiving the air from the primary heat exchanger to provide compressed air. The compressed air is sent to a secondary heat exchanger to be cooled. The compressed air is passed through a condenser and a water collector to remove moisture from the air for being sent to a first turbine.

  • Patent number: 7000425
    Abstract: An air generation unit includes first and second air cycle machines (ACMs), each having first and second turbines. A manifold is arranged between the first and second ACMs and is in fluid communciation with each of the first and second turbines of the first and second ACMs. A condenser is arranged between the ACMs and is in fluid communication with the manifold. First and second valves are disposed within the manifold and control flow of air between the turbines and the condenser. An actuator is assembly is connected to the valves for moving the valves between a plurality of positions. The valves selectively close off or prevent the flow of air from the turbines of one of the ACMs in the event that the ACM is not needed or malfunctions.
