  • Patent number: 6709474
    Abstract: A water separator is provided for use in an environmental control system that includes first and second housing portions at least partially defining an interior cavity. A coalescer assembly that may include a mesh material is disposed within the interior cavity for separating water from the air flowing through the interior cavity. First and second interlocking features, which may include a plurality of circumferentially arranged tabs received in the slots of circumferentially arranged flanges, secure the housing portions together. The tabs and flanges interlock with one another in response to moving the first and second housings relative to one another from and open position to a closed position in which the housing portions are secured to another. In this manner, V-band coupling of the prior art may be eliminated and the service time of the water separator may be reduced.

  • Patent number: 6688184
    Abstract: A flow sensing venturi system includes a venturi body and a manifold mounted thereto. The manifold is thermally isolated from the venturi body. A multiple of sensor ports are formed into the manifold which support each individual sensor and provide communication between the sensor and one or more passageways. The passageways communicate with a single high-pressure and a single low-pressure sense line. The high and low pressure sense line tap respective high and low pressure areas within the venturi body. The sensor is individually screwed into the manifold to provide an airtight connection for two independent sensor input ports. Replacement of individual sensors is thereby greatly simplified.

  • Patent number: 5784894
    Abstract: A bypass valve for use with a component of an air cycle machine is disclosed, wherein the component includes a conditioning member, an inlet and an outlet. The air cycle machine includes a component housing portion. The component housing portion defines a first volume and includes a port for receiving the valve. The valve comprises a housing for mating with the port, an air entrance opening adapted to be positioned adjacent the inlet, an air exit opening adapted to be positioned adjacent the outlet, and a valve portion for controlling at least one of temperature and pressure of the air at the outlet. Control is accomplished by permitting air flow from the entrance opening to the exit opening and bypassing the conditioning member and by prohibiting air flow from the entrance opening to the exit opening for directing substantially all of the air into the conditioning member. The valve portion is substantially entirely positioned inside of the first volume in the port.

  • Patent number: 5664760
    Abstract: A baffle insert or sleeve is disclosed for the integration of the downstream pressure tap into a pressure regulation valve ("PRY") for an aircraft environmental control system ("ECS"). The purpose of this insert is to return the flow, disturbed by the pivoting disk of a butterfly valve, to a more normal distribution within the length of the valve body. This allows the PRV downstream pressure tap to be part of the valve, instead of it (along with additional plumbing) being located four more pipe diameters beyond the valve housing.

  • Patent number: 5634964
    Abstract: An air mixer, with a water collector, is disclosed for supplying recirculated cabin air in aircraft. In the preferred embodiment: used cabin air flows over pipes of colder fresh air to cool the used air and condense out most of the moisture contained in it; the fresh air and used air are passed over opposite faces of a ring of stator vanes, thereby imparting swirls to both types of airstreams; and the streams meet at the trailing tips of the stator vanes, where they corkscrew together to throw remaining coalesced moisture against a collection trough, from where it is discharged. The airstreams can now be injected into the cabin without droplets raining down on the passengers, nor ice clogging any pipes for the fresh air, which is typically supplied at below-freezing temperature.

  • Patent number: 5133194
    Abstract: A fan inlet and diffuser apparatus (30) is provided with a lobed mixer (60) for intermixing fan bypass air (25) with a flow of fan discharge air (27). The fan inlet and diffuser apparatus (30) is particularly adapted for use in a inducing a flow of cooling air (21) through an upstream heat exchanger (20) and thence directing a portion (23) of the cooling air passing from the heat exchanger to the inlet side of the fan (14) of an air cycle machine (10), while directing the remaining portion (25) to bypass the fan (14) and pass into the central outlet flow passage (52) flowing over the mixing ejector (60) which imparts a directional swirl to the bypass flow (25) and a counter swirl to the fan discharge flow (27) passing from the fan outlet through the interior of the mixer (60), thereby enhancing the mixing of these two flows within the passage (52).
