摘要： A valve assembly is provided and includes a poppet disposed to regulate a pressure of a fluid flowing through a pathway defined between the poppet and a valve body, a drive element configured to modulate a pressure of a servo fluid to thereby control a position of the poppet relative to the valve body and an actuator body coupled to the poppet and configured to deliver a supply fluid to the drive element from a first cavity defined between the poppet and the actuator body and to deliver the servo fluid from the drive element to a second cavity defined between the actuator body and the poppet. The poppet defines a filter through which fluid flows from the pathway into the first cavity as the supply fluid.

摘要： An air cycle machine includes a turbine wheel, a turbine inlet nozzle, a valve body, and a poppet member. The turbine wheel is mounted to rotate within the air cycle machine and the turbine inlet nozzle is positioned to direct airflow thereto. The poppet member selectively extends into the turbine inlet nozzle and the valve body controls a pressure on the poppet member to move the poppet member relative to the turbine inlet nozzle to vary the size of the turbine nozzle directing airflow to the turbine wheel.

摘要： A particle separator includes a first housing and a second housing. The first housing extends along an axis from an open proximal end to an open distal end. The second housing has a closed proximal end disposed adjacent the open proximal end of the outer housing. The second housing extends from the closed proximal end into the first housing along substantially a same axis as the axis of the first housing. The second housing has one or more passages disposed at a distance from the closed proximal end of the second housing. Additionally, the one or more passages are disposed within the first housing at a distance from the open proximal end thereof.

摘要： 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.

摘要： An example compressor arrangement includes a first compressor portion configured to compress a fluid and a second compressor portion configured to compress the fluid more than the first compressor portion. The compressor arrangement also includes a motor disposed between the first compressor portion and the second compressor portion. The first compressor portion is configured to communicate the fluid to the second compressor portion along a primary flow path. The second compressor portion is configured to divert at least some of the fluid from the primary flow path, communicating the diverted fluid back to the first compressor portion along a secondary flow path.

摘要： A compressor rotor compresses air and delivers the compressed air to a downstream inlet and across a turbine rotor. A shaft rotates with the turbine rotor and the compressor rotor. The shaft is hollow with an inner bore and an outer periphery. At least one journal bearing supports a portion of the shaft, and has an inner bore spaced from the outer periphery of the shaft. A cooling air path is provided between the shaft outer periphery and the bearing inner periphery, and along a length of the bearing to at least one connection hole. The connection hole provides cooling air from an outer periphery of the shaft to the inner bore of the shaft. In a separate feature, a shaft for use in an air supply machine includes a hollow interior, with such a connection hole.
