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.

Abstract: A bypass valve (12, 14, 214) for use with a componet of an air cycle machine (10) is disclosed, wherein the component includes a conditioning member, an inlet and an outlet. The air cycle machine (10) includes a component housing portion (22). 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. An air cycle system using the bypass valve is also disclosed.
