    摘要： Systems and methods are provided for managing temperatures associated with a flow control assembly, such as a throttle loss recovery assembly. One exemplary method of operating a flow control assembly generating electrical energy in response to a bypass fluid flow influenced by an orientation of a flow control valve involves operating the flow control assembly to deliver the electrical energy to a vehicle electrical system and automatically adjusting operation to increase heat generation at the flow control assembly in response to a temperature condition, such as a potential icing condition or a cold start condition.

    摘要： Systems and methods are provided for managing excess electrical energy generated by a throttle loss recovery system. One exemplary system includes a flow control assembly to generate electrical energy in response to a portion of a fluid flow bypassing a flow control valve, an electrical system coupled to the flow control assembly to receive the electrical energy, and a control module coupled to the electrical system. The electrical system includes an energy storage element and an electrical load. The control module detects an excess energy condition based at least in part on a characteristic of the electrical system, and in response, operates the electrical system to dissipate at least a portion of the electrical energy generated by the flow control assembly using the electrical load.

    摘要： A butterfly bypass valve includes a housing defining a bypass flow passage with a pivotable throttle plate therein. An outer edge of the throttle plate in a closed position is in sealing engagement with a sealing portion of the housing such that the throttle plate restricts fluid flow through the bypass flow passage. The throttle plate is pivotable to an open position to allow fluid flow through the bypass flow passage. A port in the housing allows a portion of fluid passing through the bypass flow passage to be removed when the throttle plate is pivoted to the open position. A predetermined amount of pivoting of the throttle plate toward the open position can occur so as to allow flow through the port, while maintaining the edge of the throttle plate in substantially sealing engagement with the sealing portion so as to substantially prevent flow through the bypass passage.

    摘要： An electric motor-driven compressor includes a housing assembly comprising a motor housing and a compressor housing mounted thereto. The compressor housing contains a centrifugal compressor wheel that is mounted on a shaft of the motor rotor and also defines an air inlet that leads air into the compressor wheel, and a volute that collects the compressed air. Air bearings rotatably support the shaft. Cooling air passages are defined in the housing assembly for supplying cooling air to the air bearings. A diffuser between the exit of the compressor wheel and the volute serves to diffuse the compressed air. The compressor includes a heat shield formed separately from the compressor housing and the motor housing and disposed between them. The heat shield defines one wall of the diffuser and also cooperates with the housing assembly to define part of the cooling air passages for the cooling air supplied to the bearings.

    摘要： An air bearing assembly is provided that includes a bearing sleeve that has two slots side-by-side having rectangular profiles for engaging the ends of first and second bearing foils for supporting a shaft of a dual-stage compressor. The first rectangular-profile slot, which may be made using a broaching process, is designed to receive first ends of the first bearing foil and the second bearing foil. The second rectangular-profile slot, which may also be made using a broaching process, is designed to receive a second end of the second bearing foil. This dual-slot design replaces the complex “L” shaped single slot design of conventional bearing sleeves, allowing for high-volume, low-cost manufacturing of the bearing sleeves. The dual-slot design also provides for robust engagement of the bearing foils with the bearing sleeves, while allowing easy assembly and installation of the air bearing assemblies.

    摘要： A mechanism for differential pressure sealing for use in a compressor, such as for fuel cell applications, is described. In a dual-stage compressor, a low pressure side and/or a high pressure side of the dual-stage compressor may include a compressor wheel supported by a shaft that can rotate about an axis of the shaft. A seal carrier may be provided that rotates with the compressor wheel and includes a groove for receiving a sealing ring, which may be a split expansion ring. A static seal plate may be positioned around a periphery of a portion of the seal carrier, such that the sealing ring can seal against a contact surface of the static seal plate when received in the groove in order to create a pressure differential seal. The low pressure side may include one sealing ring, whereas the high pressure side may include two sealing rings positioned in series.
