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. An air cycle system using the bypass valve is also disclosed.
